Decals are sent in regular stamped envelopes and no tracking is provided, Tracking is available at a cost of $1.99. All decals are mailed the next observed business day and should arrive within 1 week. If you do not have it in that time please let me know and I will make sure you are taken care of. Sadly USPS does lose an envelope every once in awhile but it is still the best way to keep costs down and pass that shipping savings on to you.
