I get through a lot of these as the birds absolutely love them. These come at a great price - a fraction of the cost at all local pet stores. Delivered very quickly. Comes in a woven polypropylene type sack so very secure. I'd kept some tubs back from earlier buys so could 'decant' from the sack to lidded tubs when delivered but I guess there's no reason why you couldn't just keep in the sack - I'm sure the birds don't care!
