How do I submit a mail-in rebate?

LetterAgent can't mail a rebate submission: rebates need physical enclosures (the original UPC barcode, your receipt), and LetterAgent mails letters only. To submit one yourself, follow the form exactly: original UPC, dated receipt, completed form, postmarked by the deadline. Photocopy everything first, because processors lose submissions and your copies are how you appeal a denial.

What goes in the envelope?

Rebate forms are checklists, and the fulfillment house treats them that way: one missing item means rejection, no phone call, no second chance. Read the form twice before you seal anything.

ItemWhat they actually require
The rebate formFully filled out, signed where asked; print clearly or type it
Original UPC barcodeCut from the box, not a photocopy; this is the most common rejection reason
Original dated receiptDated inside the promotion's purchase window; circle the item and date
Sometimes: serial numberWrite it on the form exactly as printed on the product

What are the deadline traps?

Rebate deadlines come in two flavors and the form picks one: "postmarked by" versus "received by." Postmarked by means the postal service's date stamp on your envelope; received by means in their hands. If the form says received by, mail it at least a week early. There are usually two windows, not one: a purchase window (buy between these dates) and a submission window (mail within 30 days of purchase, say). Miss either and the rebate dies. And watch the one-per-household rule: two submissions from the same address, even for two legitimately purchased items, will both be denied.

Keep the product box until the check arrives. If the processor questions your submission, the serial number on the box is often the thing that unsticks it, and you cannot get that number back once the box is recycled.

Should you send it with tracking?

For a small rebate, regular mail is fine. For a big rebate on something like a laptop, tracking is worth it: if the processor claims your submission never arrived, a delivery scan turns a "lost in the mail" shrug into a reopened case. Either way, write the mailing date on your photocopy of the form so you know exactly when the processing clock started.

What if the check never comes?

Wait out the stated processing time first; rebate checks routinely take eight to twelve weeks. After that, call or write with your photocopies in hand: the copy of the form, the receipt, and the UPC. Processors keep logs, and a caller who can recite the submission date and contents gets further than one who cannot. If the company stonewalls, file a complaint with your state attorney general's consumer division or the FTC: rebate fraud is one of the complaints they actually pursue, and companies know it.
