What part of the country are you in? That will effect the price. The other thing is your description. Wet Edge and Pebble Sheen are two different products. The term "Satin Matrix" would suggest it is a Wet Edge technologies product and not a PebbleTec product. The prices between the two would also be different. There is not a Pebble Sheen selection called "Antigua", so you are not getting that product. Wet Edge Technologies originated after PebbleTec...some of the people from the original company broke away and started their own company. I personally don't use Wet Edge, preferring PebbleTec. So I can't help you on price. I suggest you check the internet for plaster companies in your area and find out a price buying retail from them.
