giant bottle of ketchup. I curse that thing every time I reach for it - it's tall and takes up a lot of space forever on the fridge door. The savings are not worth the hassle. I'm going to transfer it to a glass jar when it gets down to about 6 oz.

Ditto on lemon juice. I bought the huge bottle without thinking and rarely use it - I hit a lemon and lime bonanza and my my freezer's full of the real thing, kept in 1 oz. containers. Maybe i"ll just dump the reconstituted junk.

Steakums: lousy.
