Where can I find bulk crystal chips for cheap?

I want to go back into arts and crafts to improve my mental well-being.

I have this big idea for an art project that involves using crystal chips and mixed media, the problem is I can't seem to find a decent price for crystal chips especially ones without holes as they will ruin the aesthetic of the piece. 

I was just wondering where would be the best place to find bulk crystal chips for a good price. The more I can get the better for example 1kg or more. I have tried most of the obvious places such as eBay (Used), Vinted, AliExpress, Temu etc. but generally, I am getting around £3.50 for 200g approximately of crystal chips, is this the best I am going to get?
