When buying a new cellphone

When purchasing a cellphone and a new Bluetooth headset, DO NOT, in your haste to gather up all the trash and get it on the curb for pickup the next day, THROW OUT the box the cell phone came in.

Even if you saved the receipts, the contract, the directions,  the numerous alerts assuring you that your brain won't be fried using a cellphone and the rebate form, you will lack the ESSENTIAL element to get the $50 back on your purchase -- the bar code from the package, photocopies not accepted.

You will feel stupid.
