Re: Do you ever wish you would have waited to buy something?
It seems to be a classic syndrome. You can wait forever to get the very very lowest price, but at some point you probably want to get the item to be able to get on with using it for what you want it for.
So in that way, it's kind of about what you want the item for, and how soon you'll be needing it. If it's like "One day i am going to buy a nice acoustic"....well, take your time and wait for a great price. On the other hand, if it's like "I need a Strat for this band i'm in now" ..... well obviously you need to get one pretty soon-ish, so you'll probably be looking around quickly and taking the best deal you can find at the present time.
(both of these are assuming you have your money ready ..... obviously if you don't have the money, it's going to take a little time to get that together so you'll probably auotmatically default to the first option).
But it is just typical that the minute you've finished the research and commited your cash .... they appear all over the place at a much-reduced price soon after. At least once you know that happens so often, you can take the attitude of "meh, i don't care, i got the best price at the time and i dig this item so much i'm happy anyway, it's still worth more to me than what i paid for it".
If you're not certain that a product is exactly what you want, wait a little while for a bargain-basement price so that there's not too much pain if it turns out to be a little less than ideal for you and you can probably recoup most of your money by selling it. If it is exactly what you want, you'll be getting your money's worth even if you did pay a little extra.
Every time i buy something i think "Yeah, i'll probably see these for a lot less next month, but it's what i want and i want to use it, and at least i can recommend it to friends who might benefit from cheaper prices along the track".
