For those of you not familiar with BFG's Trade Up program, registered owners of qualified videocards have 100 calendar days from the date of purchase to trade their card in for a faster, more expensive model and pay the price difference. Now you'll be able to do the same with BFG-brand power supplies, assuming you meet the criteria.
"This program only applies to BFG power supplies purchased after June 1, 2009," BFG states. "This program may not be available to all customers, and rules/restrictions may apply. The Program is currently only available in the U.S. and Canada."
For a limited time, BFG is extending the offer to include PSUs purchased as far back as January 1, 2009. The company doesn't say how long the offer will remain valid.
