only thing that I got from IO buckets are the gel food which no fish likes to eat.

tried it and fish loved it, through it out though when realized no expiry date.

Here's my bucket of IO from around 2004 with the yellow free t-shirt sticker on the outside. Back then, the t-shirt was white with an orange logo. Not as nice as it is today. :)

In my 6 or so years reeding I've had gel food, t shirts (2 so far), and purple scoops. I think I go through about 6 buckets a year.
