Nanobag makes ultralight reusable shopping bags from diamond ripstop nylon that fold down small enough to ride in a pocket, yet each one is rated to hold 66 lb.
The saving rule that matters most here is about quantity rather than dollars: shipping turns free once the order reaches 3 bags, so the bag count in the cart matters as much as any code.
Nanobag was created by Ursus Negenborn and Rune Kippervik, who wanted a reusable bag practical enough to replace single-use plastic in daily life. The store is operated by TipTop Things Limited, the bags are manufactured in China, and returns are sent to an address in Hong Kong or to a local fulfillment partner.
The fabric measures 0.05 mm thick, and the key stress points are reinforced with bartacks and double-stitched piping. Beyond the classic tote, the range includes slings and backpacks, marketed for groceries, travel, everyday carry and the beach. For each bag sold, Nanobag funds the planting of one tree through Eden People + Planet.

Email list
Subscribing is open by email, and subscribers enter a monthly draw for a free bag rather than getting a fixed discount.
Tree planting
One tree goes into the ground for every Nanobag sold, a pledge attached to each purchase.
Seller
TipTop Things Limited runs the store, and returns travel either to a Hong Kong address or to a local fulfillment partner.
Nanobag runs on Shopify, so the discount box is on the checkout page's order summary.
A free gift is added to every purchase automatically at checkout, so that perk needs no code at all; look for it in the order summary before paying.
The store's pages say nothing about combining codes, which makes it sensible to enter one code, watch the total update, and only then try another.
Bag count also changes the bill: with fewer than 3 bags in the cart a shipping charge appears on the summary, and bringing the order up to 3 bags clears it.
Returned bags come back at the buyer's cost, so settle on colours before the code goes in.

More ways to save at Nanobag
Reaching 3 bags is the simplest lever at Nanobag, since that count unlocks free shipping on its own.
Joining the email list enters subscribers into a monthly free-bag draw, though no set sign-up discount is attached.
The return terms are worth weighing before ordering: the 30-day window covers unused bags only, return postage comes out of the refund, exchanges are limited to defective or damaged items, and gift cards cannot be returned.
Picking the right bags the first time therefore saves more than sending one back.
