Good morning,
AquaSonic could take its time selling a toothbrush on Amazon. Shoppers had the listing, images and reviews in front of them.
Then the brand moved into stores. Its founder says the packaging had just two to four seconds to make someone pick it up.
The product hadn’t changed. The moment in which someone had to understand it had.
Today:
We unpack AquaSonic’s shift from Amazon to store shelves and TikTok, cover five ecommerce updates, mark campaign changes in Shopify reports and check orders that are authorized but not yet paid.
Today’s sponsor, ABConvert, has a related question for your margins: could your “safe” price be costing you money? See the Bloon Paris price-test case and quick guide.

Could your “safe” price be costing you money?
Raising prices feels risky. What if sales drop? But keeping your current price does not mean it is the better decision.
Bloon Paris tested a $50 price increase on its US store for one month. According to the case study, conversion moved only slightly, with no meaningful decline, while gross margin per visitor rose by approximately 18%.

One price test can reveal more than conversion rate alone.
The answer is not to copy Bloon Paris and add $50. Test your current price against one alternative on a share of traffic. Keep other offers consistent, then compare revenue and margin per visitor alongside conversion rate.
ABConvert helps Shopify brands run that comparison before changing prices for everyone. Your shoppers may respond differently. That is why you test.
Today’s Deep Dive
How AquaSonic changed its pitch for Amazon, shelves and TikTok
AquaSonic first proved its Black Series electric toothbrush on Amazon.
Its founder, Arsalan Rahbarpoor, says the original product stood out because it was black in a sea of white brushes and bundled four modes, eight brush heads, a travel case and charging at an accessible price.
On Amazon, the listing had room to explain that value and customer feedback told the team what to improve.

Today’s Amazon results put AquaSonic beside established rivals at very different prices. The first image, bundle and review count start the pitch before a shopper opens the listing.
Once the shopper clicks, the product listing can do the longer explanation.
Then it had to sell from a shelf
After customers began buying another brush for family or gifts, AquaSonic expanded into physical retail.
Rahbarpoor says packaging had not been a major focus on Amazon. In a store, he had to make the product worth picking up in two to four seconds.

That changes the job of the first visual. The Amazon page can build the case over several images. The shelf has to earn the next few seconds before the shopper ever gets that explanation.
On TikTok, discovery changes it again
Rahbarpoor describes TikTok Shop as discovery-led. Shoppers respond to eye-catching colours and creator demonstrations; he says a hot-pink toothbrush became one of the brand’s best sellers there.
A search-led Amazon pitch would miss what makes someone stop scrolling.
The brush still has to deliver. But each channel gives AquaSonic a different opening to earn attention and make its value clear. Hear the founder explain the shift.
What to copy
List where customers first meet your product: search result, shelf, feed or ad.
For each, ask what they can understand in the first few seconds and what proof comes next.
Change that first explanation for the channel. Keep the product promise consistent.
Keep the product promise consistent. Change the opening to fit where the customer meets it.

In the Headlines
Etsy now requires a real, unedited product photo. Listings must include at least one unedited photo of the actual item, with some exceptions. If you use AI to make listing images, check which photo meets the new requirement.
Walmart is preparing a checkout path for AI agents. Agent Profiles will let shoppers set approval rules and spending limits. For brands selling there, accurate product information and availability will matter when an agent helps choose.
Etsy boosts the reward for seller-driven orders. Eligible Share & Save orders through January 4, 2027 receive a refund of the full 6.5% transaction fee. Use the program’s trackable links in off-Etsy marketing and check its eligibility rules.
Shopify changes how some payment options appear at checkout. Eligible checkouts with four or fewer payment methods can now show tiles instead of a list. Check the mobile experience your shoppers actually see.
Google Ads adds percentage-based customer-value multipliers. The new setting can scale a new customer’s bid value with basket size instead of adding one fixed amount. Set the value against your real customer economics, not a revenue target.
On Socials
1/ Did your new ad get a fair test? A spend floor for fresh Meta creative could help distinguish a weak ad from one that barely received delivery. Check the option and your actual spend before declaring a concept dead.
2/ A gift might do more on order two. This brand’s reported rebill result is not proof it will work for everyone. The useful test is to compare gift cost, repeat rate and contribution margin against a holdout.
The How-To
How to mark a campaign change on your Shopify sales chart
A sales spike is hard to explain weeks later if nobody recorded what changed. Put the campaign beside the data.
1. Open a time-based report. In Shopify, go to Analytics → Reports and open a report with time as its first dimension, such as net sales over time.
2. Add the event. Select Annotations → Create annotation. Give the campaign a name, choose its date or date range, and select an appropriate category.
3. Record the change. Note the offer, audience, price or spend that changed. Save the annotation, then compare the trend before and after.
You need Reports permission to create an annotation. The marker gives your team context; it does not prove the campaign caused the movement. Shopify’s instructions are here.
Daily Growth Rep
💳 Today’s Growth Rep: Find orders you haven’t charged
If your store captures payments manually or on fulfillment, check orders marked Authorized. That means the payment is approved, not yet collected.
Why this works:
Authorizations expire, so a fulfilled order can become harder to collect.
A saved view turns this into a repeatable cash-control check.
Your rep:
In Shopify Orders, filter Payment status → Authorized.
Open the oldest and any marked expiring. Confirm fulfillment and fraud checks before capturing payments that should be collected now.
Save the view and, if applicable, enable Shopify’s one-day expiry warning.
Report: “Authorized orders checked.”
If you capture automatically at checkout, this rep does not apply. Shopify explains authorization and capture here.
