Amazon DoorDash $50 GC 15% off x 5

First, figure out what you're actually going to do with these five gift cards. If you already order from Amazon regularly and happen to use DoorDash, 15% off saves you a limited amount, but the upside is the low barrier to entry. Costco's 20% off is genuinely a better deal, but you need a membership and you have to catch it when it's in stock. My advice: compare against what you actually need first. Don't stock up just because of a discount—buying too much ties up your cash flow.

Whether this deal is any good depends a lot on which state you're in and whether you use DoorDash. Around here, DD's coverage is so-so, and gift cards don't necessarily arrive quickly, so I probably won't bother—I'd rather wait for Costco to restock or just use a cashback card.

If there's a five-ticket limit, you're only saving a few bucks anyway—hardly worth the time it takes to go there.

Instead of getting caught up in whether DD or Amazon offers bigger discounts, it might be better to flip the question: the real issue with this post may be whether "discount channels" are even worth the effort to monitor. The Zift route adds an extra layer, essentially trading a discount for operational complexity—and if something goes wrong, you're on your own. If you're just testing the waters with a small amount, that's actually more practical than chasing a 15% off deal.

I'd suggest starting with a small test order first, and only consider scaling up once you've confirmed the redemption and crediting go through smoothly — provided this channel offers clear refund or customer support. Otherwise, if you go in with a large amount, you can easily get stuck halfway.
