Nope, you're not missing anything.
I've used them for a while now without issue because they often run 80% off promotions. I would just recommend you check a few things:
- How often can you use one for that particular restaurant?
- Can you eat $X amount of food to make it worth it? We have purchased for restaurants we weren't familiar with only to find out we would have to order 4 entrees to make it worth it. Now I look at the restaurant menu online before buying a GC for a new restaurant.
- Read the fine print. Alcohol is not usually included, some have other specific requirements, and not all $25 GCs are off a $35 purchase.
- When you do use it, see if the server added gratuity without letting you know. I find it a horrible practice, but I've had situations where the server didn't let us know. Not a huge deal since I saw it, but I think it's sneaky, so I want to mention it. (You should tip on the total of the meal before the cert, but I think a server should be honest and let you know they added gratuity.)
I have purchased several for out-of-state vacations we've taken, too.
When I do this, if I have leftover certs, I just post to the local CL and someone always takes me up on it.
