Very true. You have to weigh all the options. I just ordered some saucers to put under pots. The $ hurt, but the odds of finding enough used ones that are fairly similar looking were very low. It was worth it to just bite the bullet and get it over with so I can use them this summer.
After Jon mentioned Craig's list, I went and looked. Sure enough there were some large pots of varous sizes that were a decent enough price. But I've gotten no reply to my reply. So now I wait.... Were they sold? Has the guy just not opened his email yet? Is he a serial killer?
I don't much like the uncertainty. But it if works out, it would be great. I'm not counting on it however. If this happens a few more times, that $100 for fifteen 15gallon pots is going to seem more reasonable. :)
