I need 5 gallon buckets or 20 liters or somewhere thereabouts with tight fitting lids. Not the buckets you find at Tesco or Home Pro but something more durable than their offerings and again lids that fit tight. Is there anywhere worth checking for such things?

I'll tell you where to get some fine five gallon buckets with tight lids -- some of the best I have seen. Go to Makro and buy three buckets of laundry detergent. They use Western-style marketing -- the buckets are only one-third or less full. Open them all and consolidate into one and, voila!, you have two buckets and a year's supply of laudry detergent. This is a good and inexpensive solution unless you need a whole lot of them.

I use these buckets for storing anything I want to remain absolutely dry or protected from ants. Electronic components, for example.

Are you brewing something?

If you are you will need to look at food quality plastic and not detergent buckets.

Food grade is not needed. I don't know how much the Makro option is humor though will check as a last resort so please keep 'em coming. I would think Thailand, land of plastic there would be many great places to buy.
