For example, at the end of the summer or winter season, many retail outlets have sales during which goods are sold at a reduced price. Sales are temporary. Your phrase 'discounting market' doesn't really make sense. If you bought it at an outdoor/indoor market, you could say maybe 'a discount stall in a market', or if it's from a shop/store, you could say 'discount store'. These are places which sell goods at discounted prices all year round. I hope that helps.

Both are the deduction of original planned sale price. Usual cost is deduced
