If you take a look at Best Buy's newest price match policy which was updated today, it states the following:
Does the HP TouchPad tablet qualify for the Price Match policy?
No. The HP TouchPad is on clearance and we will no longer be selling the units so we will not offer any price matches. We do offer a 60-day return/exchange policy for this product.
Read that carefully. "We will no longer be selling the units". Interesting. Looks like HP took back all those Touchpads after all.
