What are your "given our import customs limit"?
If limits not an issue, based on what your said, I would get a chest freezer, try to get a volume discount or reseller discount, and stock up. Rotate your stock as you use it, first in, first out.
I think it starts at $1000 when taxes, customs duties, import fees etc. get added on, and I think from memory it adds about 30% to the price. I already planned to get a volume discount :-) Thanks for the tips :-)
