I feel the same way as you do about the guilt. I've been sitting on my buying power for weeks now, watching the price trickle down. I could've bought at 0.15 (which already feels like a bargain) and then told myself I'd wait on 0.10, the pps during the plummet as a result of the Amazon panic that I had no money to take advantage of at the time. Now we're at ten cents, and I still find myself waiting.
