I bought a groupon for Window tinting for up to 5 windows. When I got to Foss in Tacoma, the employee said that the groupon was only for the lightest tint and didn't include taxes. If I wanted darker tint, I would have to pay more. I ended up paying $66.00 more. This is deceptive and very bad business practices. Buyer beware. I will not return to this business. Also the waiting area was filthy.
