You can get some nice stainless steel stock pots from Walmart for under $10, 8 quart I think. They are a thinner steel, but work great for soap and lotions and shampoo (etc). I picked up 2 of them and absolutely love them! They were $6.99 before taxes. I also got some nice silicone spatulas for around $1 a piece.
You can also get cheap spoons, spatulas, and measuring vessels from Big Lots for great prices, and a lot better quality that the dollar store (I always worry about dollar store products with so much lead and mercury in their items... even plastics!).
Five Below is also a great place to pick up soaping stuff, if you have one nearby.
Also, check sales tables! I picked up a $40 knife set for $10 at Target because the box was torn! Also got a dozen stainless steel teaspoons for $4 because the handle pattern was discontinued.
The $1 section at the front of Target is also a great place to check. I've gotten mixing bowls, small measuring vessels, small measuring bowls, and some little dishes for mixing colourants in all from this section! As well as some organizational stuff. The majority of it was 2, 3, or 4 for $1!
If there is something specific you're looking for, PM me and I will let you know where I got mine, or where I have seen it. I'm cheap. Not even thrifty... darn right cheap LOL.
I'll help if I can!!!
