Nowadays, rebates have become something you get for every purchase you make on any electronic items and computers. Rebates of over $20, $50 or $100 are not uncommon.

There are even items advertised as "free after rebate". But there are catches to watch out for, if you are careful they can help you get some really good deals. The rebate works like this you pay the listed price for an item then mail in a form and the bar code to the manufacturer and they send you a refund thus reducing the price of what you paid for the item except with a time delay of several weeks.

Rule #1. Rebates that you get from reputable companies are usually just fine.
You can be always sure of rebates that you get from Best Buy, Amazon or Dell but you should probably not count on getting one from a company you’ve never heard of. If you really want the product and are OK with paying the price listed then buy it but don’t count on actually getting the refund.

Rule #2. Check rebate expiration dates.
Many times products will stay on the shelf of a retailer after the date for sending in the rebate offer has expired so check that date carefully.

Rule #3. Be sure you have all the forms required to file for the rebate before you leave the store.
Rebates will almost always require a form to be filled out, a receipt for the purchase and a bar code.

Rule #4. Back up your rebate claim.
Make copies of everything you send in to get your rebate including the bar code. Stuff gets lost in the mail all the time and if the rebate is for $50 it’s worth the trouble to back up your claim.
