I love a good yard sale and have been very lucky. I bought plastic pond very cheap at one, at another I picked up 10 gallon tank for $3. At goodwill I found a old ornament for a fishbowl $1. I looked it up on ebay and can not believe how much some of the old fish tank ornaments sell for. Driving to my dentist one day a 55 gallon tank was sitting curb side with free sign, gave that to a friend. What great finds have you made ?
