Original base price $48k pool/spa bid included base white plaster. Optional upgrade showed pebble tec for $6720. I was told that was the increased price above what the white plaster would be (@$2800). From everything I have been reading and sinced learned that seemed pretty high. In looking into upgrading color -- midnight blue @$2800+ I have now learned that the $6700 was the original total price w/ PB markup for the pebble tec w/o any credit for the base white plaster. The PB is now telling me the contract should not have stated "add to base". I am kind of frustrated by the whole thing -- and pebble tec only allowing 1 installer in area thus no competitive bidding doesn't help ($10k+ for ocean blue pebble sheen). So do I just say forget the + $6700 on the pebble tec and go w/ gray plaster +$600 or maybe look into other products i.e. wetedge or ???
