We do not put your order into production until you reply to the confirmation letter. You would be surprised how often customers order the wrong model, or change their minds, or the dimensions that we have don’t match their cabinet, or they decide that they’d rather have a clamshell than a cover, or… It goes on and on. We send the confirmation letter with the dimensions because we want to cut it out and do it right THE FIRST TIME! It’s very expensive to correct a mistake after the bag or cover is made. Measure twice, cut once. GET IT RIGHT THE FIRST TIME! If we don’t hear back from you within 3 weeks we may cancel and refund your order, or we may proceed if it’s a common item but cannot be held responsible if the cover or bag does not fit.
