Discounts and Sales are good words, but isnt it complicated to calculate the discount percentage, or find out how much money youll save?
Off course you have just to take the original price, multiply the discount and subdivide one hundred, round the result and finally subtract the result from the old price... or you just start SaleCalc, input the price, push the % button and insert the percentage and youll get the original price, the discounted price and the amount of money youll save!
