Craft stores like Michaels can be cheap, if you use their coupons. But you usually have to do it one at a time, and it's still not super cheap.

For REALLY cheap frames, you can get a 4-pack of varying sizes for $1 at the dollar store. I have hung several galleries of our vacation photos using those 25-cent frames. The quality is what you'd expect, and if you knock them onto the floor they break immediately.

For affordable-but-decent-quality, I use Craig Frames on Amazon. Almost any size is available and I think they look beautiful. Those are the frames I am using to hang all the art prints for LO's nursery and most of the posters and art in our home office. http://www.amazon.com/s/ref=bl_sr_home-garden?ie=UTF8&field-brandtextbin=Craig+Frames+Inc.&node=1055398

Goodwill!!!

Michaels buy 1 get one frame sale. And IKEA.

Ikea. Reasonable quality, good prices.

Have you checked Ross? I'm not sure if they are all over the country or just on the west coast. Or maybe TJ Maxx, Marshalls.

Hobby Lobby has 50% off all frames right now, I just got a couple yesterday for our bathroom and our living room. As for a variety you can find some at Walmart/Dollar Tree and spray paint. I find that the best frames for a gallery wall are mix matched to give it variety! Buy a couple fun patterns/colors and then use the basic cheap ones from Walmart to balance them out!

Hobby Lobby or Michael's. They're always running some kind of promotion or have a coupon you can use.

I love the cheap, really flat, minimalist looking frames from Ikea!
