Cheap Black Sand?

I'm planning on using Black Diamond Blasting Sand 20/40 grit, but I was wondering if there are any comparable black sands at a good price.

 

Check ebay. You may be able to find aquarium sand at a discount price.

 

I actually just found Black Diamond Blasting Sand 20/40 at a great price!

 

Black diamond is the best price. $8 for 50 lbs. can't beat it.

I actually found it for $7 at Rural King!

 

We don't have that here. I need some sand too. Although $8 is still a steal. Sooo cheap!

Looks like I'll be getting mine from Tractor Supply as well. Rural King doesn't have it in stock near me. I look at it as a 50lb. bag will cover 2 20Hs for me at $4 a tank.

 

I had to go to 3 different Tractor Supply stores before I found one that actually had it in stock. They keep it in the same aisle as the welding supplies. I'll be using my bag in a 20L.
