EOS30 takes 30% off at extrabutterny, but it won’t apply to everything in your cart. I tested it myself on four items, a Y-3 jacket, two Puma x A$AP Rocky balaclavas and a pair of Straycats in a size 8, which came to six hundred and forty dollars at full price.
The code pulled that down to $493.00, so I saved $147, or about 23% of what I walked in paying. It came out under thirty because the sneakers didn’t take the discount at all.
What Discounted And What idn’t
- Y-3 Chito Graphic Running Jacket (M): $330.00 down to $231.00, tagged EOS30 (-$99.00). Exactly thirty percent.
- Puma x A$AP Rocky Knitted Balaclava (x2): $160.00 down to $112.00, so forty-eight off. Also exactly thirty.
- Puma x A$AP Rocky Straycat Shoes (size 8): $150.00, unchanged. No tag, no strikethrough, nothing.
The Sneakers Are The Catch

Both Puma pieces came out of the same A$AP Rocky collab and only one of them moved, so this isn’t a brand restriction. Either footwear is carved out or that specific release is, and I can’t tell you which from one cart.
Either way, price sneakers at full when you’re working out whether an order is worth placing. My jacket on its own was two thirds of the whole saving.
Putting The Code In

The field sits in the right-hand order summary, Discount code or gift card, then Apply. It shows up as a chip with the per-item tags appearing underneath.
Watch the express checkout row at the top. Shop Pay, PayPal and Google Pay all sit above the email field, and if you tap one on autopilot you go straight past the code box.
Before you commit, sale items here are final sale. No returns. Fine on a one-size balaclava, risky on a $330 jacket you’re guessing the fit on.
I’d use this on outerwear and accessories and stop expecting anything from the footwear side. EOS tends to mean end of season and it’s late August, so I wouldn’t sit on it too long either.
