How to Redeem a PerkShelf Coupon, License Key, or Upgrade Link
Delivery is a string in your order. Redemption is on the vendor's site. Pick the plan row the listing names, confirm $0 due if it is a coupon, and do not apply a code to the wrong tier.
PerkShelf does not log into Lovable, Warp, Google, or any other vendor for you. You receive a payload. You redeem it on an account you control.
Three delivery types
- Coupon / promo code: You open the vendor pricing or billing page, select the plan the listing names, enter the code, and submit. Many processors still require a card even when the discounted total is $0.00.
- Promotion or upgrade link: You sign into the correct vendor account first, then open the unique link. Google AI Pro 18-month upgrades work this way. No PerkShelf card is collected.
- Ready login: You receive credentials. Sign in, change the password immediately, then use the product. iLovePDF Premium and Microsoft 365 A3 are this type. The pregenerated username is not yours to rename unless the listing says otherwise.
The $0 card check
Stripe, Chargebee, and similar processors treat a $0 invoice as a real checkout. A virtual card with a small available balance is enough when the vendor only authorizes $0. If the cart is not $0, stop. You selected the wrong plan row or the code did not apply.
Pick the named row
A Linear Business coupon does not belong on Basic. A Resend Transactional Pro coupon does not belong on Marketing. A Readwise full-plan coupon does not belong on Lite. If the named row is missing, do not pick a neighbor row to force it. Open a ticket or message Telegram support.
After it activates
Confirm the term and plan name in the vendor's own billing screen. PerkShelf will not see that screen. If the vendor later bills you, that is their saved payment method, not a PerkShelf rebill.
Worked examples: Lovable Pro, Warp Build, Google AI Pro 18 months. Product pages keep the live price and stock.
