Amazon has it for the same with free shipping for Prime members.) Choose in-store pickup to avoid the $79 truck delivery fee. That's tied with our mention from three weeks ago and the lowest price we could find now by $8. It's constructed of 4mm structural foam and features an integrated water seal.
