They don’t actually run a customer referral program on the site. Since it’s basically Fanatics, your best bet is having your friend open an incognito window to trigger the first-time email popup for 15% off. Honestly, check the header banner first. They run 20% to 30% off promos on most weekends anyway.

The promo box on sportsmemorabilia.com is right below the cart summary, but heads up: most sitewide coupons exclude the actually good stuff. Anything authenticated by PSA or Fanatics usually gets blocked at checkout. Your best bet is signing up for their newsletter for the 10% welcome code, or just checking Fanatics directly since inventory overlaps.

SportsMemorabilia.com is run by Fanatics, so a lot of signed jerseys and helmets get excluded from their standard sitewide coupons. Check the checkout page—military and first responders can usually get 15% off through ID.me. Just make sure whatever you buy has a legit COA from PSA or Beckett.

Sportsmemorabilia.com doesn’t do birthday codes at all, sadly. Since they're essentially under the Fanatics umbrella, your best bet is opening an incognito window to grab their 10% new-subscriber code. Just check the fine print at checkout, because high-end signed gear usually gets excluded. Or let it sit in your cart overnight.
