After gaining 3 quotes for our she we decided on shed bonanza. After this nearly every aspect of the quote cost increased. The concrete went up nearly 150% from the preferred concreter. They did not supply information to be able to get an alternative concrete quote and only supplied one from the preferred supplier after we had paid our deposit. They tried to wash their hands of it saying it was not their responsibility. We cancelled our shed and after many discussions they return our deposit. Never again with shed bonanza
