Sell-It-Cheap salesrooms organises general and specialist sales where items are sold to the highest bidder. There is a sliding scale of commission charges, based on the price of items sold, with lower-priced items attracting a higher percentage. All items sold have a price in multiples of £1. Items sold for £150 or less attract a flat-rate fee of £7.00, items otherwise sold for less than £500 have a fee of 6% of the price realised. Items otherwise sold for less than £1000 have a 4.5% fee, with items otherwise sold for less than £5000 having a 3.5% fee. Any items sold for £5000 or more have a 3% fee. Following customer feedback, Sell-It-Cheap have decided to change one of the existing commission bandings, with items sold between £500 and £749 having a 5.5% fee, and items otherwise less than £1,000 having a 4.5% fee. What tests would be appropriate to test this change in commission bandings, using the 2-point boundary value analysis technique?
