[Off-Topic] Other deal subreddits like FMF?

I love r/FrugalMaleFashion. Since finding it earlier this year I've bought a ton of stuff I don't really need for incredible prices. I'm a huge fan of SlickDeals as well and do the same due to them. However, I was thinking today, I could really use more sources of great prices for me to get in trouble with my fiance for.

Are there any other subreddits that people use to find great deals on other shit? I'd love to add them to my daily time and money wasting routine!

Thank and keep spending frugally!

Edit: Thanks for all the suggestions guys, keep them coming. One I'd like to suggest if r/giftcardexchange. it's fucking awesome, if you got a purchase your planning on making you can easily get giftcards for about 80% cost. It's great if you got the time to search and make deals. Especially for bigger purchases.
