Dianne Moller has some great food storage solution containsers.
I will also be passing around the list for the cadbury chocolate buttons. The list is for milk,dark,and white buttons which are all quality chocolate, not compound. Buttons are bigger than chips but smaller than melts. Purchase by the kilo and the costs are on the sheet. They store well, and will store longer if you freeze them in a zip lock bag.
Speaking of freezing items, a tip I picked up from the last welfare enrichment was to freeze(over night) flours and rice before you store or use them as this process kills any traces of weevels and other micro organisms which are present - talk about piece of mind!
