Stanford, California
$18
Bought this automatic plant irrigation kit before for an extended trip before, but don't have the need for it any more. If you travel very often or forget to water your plants, this is great tool to make sure your plant survives. Condition is used like new. It seems that it would be $40 before tax on Amazon, so $18 is a good deal. I can drop it off on campus even though I don't live on campus.
