Chillax!
1. The ad advertised a Thanksgiving blowout starting tonight, Wednesday, 11/25. There's still plenty of time between now and the end of Thanksgiving or even Black Friday.
2. It's a "Black Friday" deal so there's bound to be some madness attached to it. Think of all the people waiting in the cold in lines outside brick and mortars. You're sitting at home searching and refreshing a website. It would've been nice if the Target gift card deal went live exactly at 9 PM PT/Midnight ET, but I wouldn't be surprised if it starts in the wee hours of the morning and it still wouldn't be false advertising.
3. When Gift Card Mall ran the sale on Target gift cards on Monday, it took almost 4-5 hours for them to sell out. I know because I was able to get in when they were 94% sold out hours after the first time stamped post about the deal appeared on Disboards. If you check back frequently, you'll have a good chance at getting in on the deal.
4. Just because Gift Card Mall ran a sale on Target gift cards on Monday that moved 10,000 units, doesn't mean they won't offer this deal again. This is GCM's entire business, and they sell discounted gift cards to various businesses all the time.
5. As for gift cards to Target, $185 for $200 isn't even that great of a discount. It works out to just 7.5% -- a discount or close to it that you can sometimes find on Raise or Cardpool. Not to mention it's likely to be limited to 1x gift card per account. So really, you're getting upset over $15.
6. Based on what I've seen in the past six months or so, it seems GCM runs $95 for $100 or $92.50 for $100 Target deals often, about every 1.5-2 months. Even when GCM isn't offering a discount, eBay seems to run eBay Bucks bonuses frequently enough that you still come out ahead or better buying from GCM at full price with shipping during these promotions.
