While searching for a Pioneer AJ center channel speaker deal (which I didn't find unfortunately) I found the Bookshelf pair for a great price! Google Express has the Pioneer SP-BS22-LR 2-way Speakers (pair) for $129.99 which itself is the cheapest i have seen.
Then use the 20% DAD20 (max $20) coupon (or existing GE members would have a better 20% off coupon - max $100 already) for $104 before tax. Also, as a bonus, if you are an AMEX card holder you could do this
Note: coupons expire on 6/17.
