OWC offers rebates on memory!

A rebate from OWC on your old memory module helps make upgrading to higher capacity chips even easier! From the date of purchase of a qualifying new memory module from OWC, we allow 60 days for you to return your old memory for a cash rebate! Once you've received and are satisfied with your new memory, just fill out our online rebate form or contact OWC Customer Service for a rebate RMA.

Please allow up to 14 Days from the time we receive your memory for testing and rebate processing. Your memory must be functioning correctly to qualify. Upon successful testing, a rebate check for the qualifying amount will be mailed to the billing address used on your new memory module purchase. It's that easy! :)

When you upgrade your memory from Other World Computing, a rebate for up to the same number of memory modules purchased is available for the return of your old module or modules! Module(s) must be in working order.
