So, what do y'all do?
Really the only area I've been able to do anything is gas, mostly via GasBuddy. If you're not familiar with GB, it's an app that shows you gas prices in your area, plus they offer a debit card that you use for a 5¢/gallon discount. A fun thing is that this can be combined with other discount cards, like KickBack to get even greater of a discount. It won't work with other payment cards that offer discounts, only basic discount cards.
I consider the card safe to link to your bank account, it's handled by Western Express aka WEX, a company you might've seen around for fleet fueling, think semis, although they've expanded beyond that.
Since GetUpside came out, they've also added deals to the app. Both services offer similar discounts, with GB's advantage being that card I mentioned, since unlike GU, there's no reimbursed, just pick a deal on the app, go buy your gas, and the discount will be applied before your bank account is charged.
The only other discount I regularly use is my Sip Club membership at St Louis Bread Company (Panera Bread Co). For around $12/mo or thereabouts you get 'unlimited' free drinks, unlimited in as much as one free self service drink every two hours. That's soda, coffee, tea, etc, and always log in for your drink, using your membership properly gets other discounts, especially if'n you buy things, even as little as a muffin. Hey, if'n you're on the road, you gotta drink, and at a place where drinks are $3+, the membership pays for itself real fast.
So, what else you got?
