i've been using gyft since 2013 and egifter since 2017. those are my go-to gift card malls. i've never experienced a single problem with either site. egifter also provides discounts depending on payment method---for example, it's 2.5% off uber eats cards when you pay with crypto.

since both sites pulled amazon.com gift cards, i had to look elsewhere for them. one option is the bitpay wallet, which has a built in gift card mall. i've used it dozens of times without issue, but one time i had a frustrating issue where a card wasn't delivered and it took a week to resolve.

after that experience, i started using bitrefill for amazon.com gift cards. they are unfortunately the most expensive option by far. they charge an extra 2% on everything. they do have the added bonus of processing with zero confirmations (make sure not to use RBF though!) if you pay with 6+ sat/byte fee rate, so i always use them when i'm in a hurry. however, i'm getting sick of being overcharged every time so i might go back to the bitpay wallet.
