Customer is on 4.30 and is trying to set item pricing tiers in inventory. Wants to set qty from 1 to 9.5 (vs 10). The tiers won't let me enter decimals even though we have qty decimals set to 2 or 3. I tried this in 4.5 too and same thing so can't use that as excuse to upgrade. Is this working as designed or why can't I enter decimal numbers? Any solutions?
