ATM Collection currently offers two straightforward paths to savings: a 20% off promo code that applies to your entire purchase, and a free shipping benefit on orders over $50. The 20% code is the main discount option and works on most purchases, while the free shipping deal suits smaller orders or when you have already found what you need.
For orders under $50: If you are buying a single item or small selection, the 20% off promo code at the top of this page is your best choice. On a $40 order, for example, the code saves you $8, bringing your total to $32 before any sales tax. For first time customers, the newsletter signup offers 15% off instead, which would save $6 on the same $40 order, so the 20% code is the stronger option unless you already plan to subscribe for future deals.
For orders between $50 and $249: The 20% off promo code remains your best savings. On a $100 order, the code saves you $20, bringing your total to $80. At this size, free shipping over $50 is useful only if you were factoring in a shipping charge, but the promo code's 20% discount will almost certainly save you more money overall.
For orders over $250: The 20% promo code is still the leading offer. On a $300 order, the code saves you $60, bringing your total to $240. This is substantially more than the free shipping benefit alone, so apply the code unless it excludes the items in your cart.
For the Better Together bundle collection or Essential Tees: ATM Collection runs separate 20% sales on specific product lines: the Better Together Bundle Collection (men's and women's paired pieces, available through December 31) and when you buy 3 or more Essential Tees. These are automatic discounts with no code needed, so if these product groups are what you are shopping for, the 20% saving applies at checkout. Neither can be combined with the promo code, so you cannot use both on a bundle or tees order.
For full-priced women's recycled cashmere: A third 20% promo code applies specifically to full-priced items in this category. If you are buying cashmere from ATM Collection and you see this code listed, it will take 20% off, again at no reduction if you try to layer it with other offers.
The codes at ATM Collection cannot be stacked, so choose the one that applies to your items: the general 20% code works on most of the range, while the category-specific codes offer the same saving on narrower selections. Compare the final price after applying the most relevant code and take whichever leaves you better off. In the 12 months to October 2026, ATM Collection has offered one promo code, with the biggest percentage discount in that period being 25% off in January 2026, so the current 20% is a solid saving but not the largest the brand has run.
