I use to advertise DW's for $55.00. w a disclaimer, that said "average size driveway" These driveways were the size that no more than 4 cars could be in at a time. Double lane 2 cars. I got tons of business out of it, and always got the house, back patio, front entry, always something extra. This was 15 + years ago though and helped to build my business. 25$ now a days, I don't know, that's a big risk to take hoping to build on the sale.
These are called ADV specials, just like what furniture and appliance sales in the newspapers are. Walk in any furniture or appliance store with their weekly advertised specials and inquire about one and see how fast they try to step you up. Often time they don't even have them in stock.
