You can
put this solution on YOUR website!Well, most (if not all) retailers do the sale procedure as stated in (A).
If your the buyer you might think you're getting cheated of the "sale" price, because the tax is excluded! They put the tax after they discounted the selling price, not discount the item after they put the tax on top of it. Whooo!
Logically, it make sense if you think the business part of it to do as stated in (A). Why?
Simply because the one on sale is the SELLING PRICE, NOT THE TAX WITH IT. Think about it, there was never been a percentage off on a "sales tax" unless you don't pay it at all right?
If your the retail store, you want to do (A) and it's just the legal way.
If your the consumer, of course you want letter (B) --- more deductions eh!
Thank you,
