Apple Inc. will give a refund of $100 back to shoppers who bought the first-generation iPad at one of its retail stores or through its online store in the past two weeks.

Online customers who already made their purchase must call Apple customer service to process the refund. In-store purchasers must possess the receipt in order to get the refund.

People who want to return their first-generation iPads can do so within 14 days of purchase.

This Apple policy kicks in when the company permanently reduces the price for one of its products. Apple unveiled a new version of its tablet computer, the iPad 2, on Wednesday. At the same time, it cut prices for old iPads by $100, the AP reported.

The first-generation device now ranges from $399 to $729, depending on the model. The new iPad, which starts at $499, is thinner and lighter. It also features a faster processor and front and rear cameras.
