Where To Buy DIY Supplies?

I prefer to get my DIY supplies at the cheapest price. I normally make a stop at Walmart if I'm in need of some quick supplies such as Mason Jars paint, etc. When it comes to finding objects such as ping pong balls, I couldn't find them in any store near me. I get most of my supplies from Amazon because I earn several Amazon gift cards from online sites. I end up spending less on there than I would at an art store such as Michael's. You can check previous posts to see how you can earn money or gift cards online or on your phone!
