Good question.... I haven't really gotten around to checking on the cost of the pavers. The area in question, though will be covered with a garage I'm making plans to build in the next couple of years, so I really don't want to put anything permanent there at this point.
I like the look of the pavers versus the concrete as there are several walkways around the house, all of which have old, patched/discolored/sunken concrete and also want to reconfigure a few areas.
Part of the reason I'm curious about whether the offer is fair is because I want to build a 16'x20' parking pad next to the current small garage, and would be able to use some of the credit. If, for some reason, that doesn't work out, I have some old concrete stairs that I want to remove and replace with wood (as they were originally) and will need to replace the old and cracked concrete pads with new.
