Just saying, I don't think stores should have to stop selling sand, just present warnings of use. I switched over to sand once my beardy became 3 and wasn't missing any prey items any more. As long as one takes the time to spot clean and the beardy is not at risk of impaction(improper husbrandy, calcium deficieny, bad accuracy), I think it's fine to use, though using say purple id bet be pretty annoying to find out your beardy has become a grape. However, I may try out excavator clay because it has quite the appeal(you can make shapes, sometimes beardies can dig, almost no risk of impaction for any aged beardy if used properly, etc).
