Direct US Shopping vs New Zealand Resellers: Is the Summer Fridays Birthday Cake balm actually worth the shipping costs?

Why the Summer Fridays Birthday Cake Balm is everywhere in 2026

It is April 2026, and the obsession with the Summer Fridays Lip Butter Balm in Birthday Cake hasn't slowed down since it first appeared as a 'Rising Star' on TikTok. This limited edition flavor has become a bit of a cult legend, specifically because it smells exactly like a fresh vanilla cake and leaves a subtle, shimmering pink finish that is hard to replicate. While most of the permanent line is available globally, this specific flavor remains a US storefront exclusive.

Just a moment, securing your connection...

For those of us living in New Zealand, the FOMO is real. Looking at current us trends, this balm sells out within minutes of a restock. Because it is so limited, local stockists in Southeast Asia and Oceania rarely get a whiff of it, leaving Kiwis to wonder if they should just stick to the Vanilla Beige or actually try to source the real deal from the States.

US Exclusives vs New Zealand Resellers: A cost comparison

If you look at local marketplaces or social media resellers in New Zealand, the markup on the Birthday Cake balm is often double or triple the retail price. You might find someone selling it for $80 or $90 NZD plus local courier fees. When you compare this to the US retail price of roughly $24 USD, the price gap is massive.

By using a freight forwarder, you can access the US site directly. Even when you factor in the cost of a international shipping service, buying two or three balms at once (or adding them to a larger Sephora US haul) usually works out much cheaper than paying a local scalper. Plus, when you shop us store directly, you know you are getting a fresh, authentic product rather than a potentially expired or counterfeit version from a third-party seller.

Shipping Estimates: Weight and Dimensions

To help you plan your haul, here is a breakdown of what you can expect when this item hits the warehouse. This is essential if you want to use a shipping calculator to get a precise quote.

• Estimated Box Weight: Approx. 0.2 lbs (0.1 kg) for a single tube. Even with protective packaging, it is incredibly light.
• Estimated Box Dimensions: Small. Usually shipped in a padded mailer or a very small 15cm x 10cm x 5cm box.

Volumetric Weight and Battery Check

The good news for beauty lovers is that lip balms are high-density, small-volume items. Unlike a large plush toy or a designer handbag, you do not need to worry about a high volumetric weight charge. The actual weight will almost always be the same as the billable weight.

Additionally, this product contains no lithium batteries or hazardous liquids that would trigger restricted shipping fees. It is a straightforward, easy-to-ship item for any package forwarding service.

How to get your balm delivered to New Zealand

Since the Birthday Cake edition is only on the US site, you will need a tax-free us address to complete your checkout. This is where comGateway comes in. You simply sign up, get your US address, and use that as your shipping destination on the Summer Fridays or Sephora US website.

If you have never done this before, here is a quick how it works summary: Once your balm arrives at the US warehouse, you will be notified. You can then choose your preferred courier for your New Zealand delivery. This gives you the flexibility to choose between speed (like DHL international shipping) or a more budget-friendly option.

Understanding Import Tax and GST in New Zealand

Before you hit the buy button, it is important to remember how New Zealand handles overseas purchases. Since 2019, New Zealand has required offshore retailers (or the shipping service) to collect 15% GST on low-value goods (items under $1,000 NZD).

You should factor this into your budget. While you likely won't deal with a heavy import tax or customs duty for a single lip balm, the 15% GST is standard. Check our guide on import duties if you are planning to bring in a larger shipment of electronics or luxury goods alongside your beauty products to make sure you stay within the tax-free limits where possible.

In the end, if you are a fan of the formula and want that specific Birthday Cake scent, the direct US route is the most reliable way to secure it without the NZ reseller tax. It’s a small luxury that’s much easier to get than you think.
