This GTX970 card was @ ~$560 yesterday and now its $624. I've seen stores raise prices before sales, but is it even legal to raise your base price in the middle of a sale (20% off ebay sales)?
Oh no, a company trying to increase profits, never seen that before!
Rather than just the increase in price, the main problem would be that their own site lists the RRP @ $549. That's the main problem in play here
