define decent after cost of $ since you infer they paid up front to get max discount......
First of all, I did not "infer" that they paid up front. I said if they pay "within terms". Since, apparently you don’t know what that means, (even though you worked at three stores), I will explain.
Most companies have a NET 30 invoice. Which means you have 30 days to pay the invoice in full, but most offer "terms" which if paid, (usually within 10, 15 or 20 days) you get the same discount if you paid up front or prepaid the order. So you don’t necessarily have to prepay for the order to get the discount. There will always be exceptions, but this is how it works for the most part.
Most of these discounts are in the 3%-8% range, (some even more, but that’s about the average).
Sorry, I should not have said decent "margin", but decent "profit". Granted the margin will be much lower than selling at full retail.
Again, I will not get into specific dollar amounts.
