@Burton, sorry. You're right. My examples don't amount to 1/3rd the price. I misread your post as "1/3rd off". My bad on that one. I may have read and posted a bit hastily.

I would agree that one can't just find any given part on the Internet for a deep discount. If one wants the deep discounts, imho, one must be willing to compromise and settle for whatever it is that happens to on sale at any given moment, which might mean last year's parts, or something that's not trendy, or some technology that is on the way out.
