Can't stand plastic ham tbh, for us 'nice' ham is the dry cured stuff, either prepacked or from the Deli. The deli stuff is actually cheaper iirc, but I find they precut DS2's favourite (crumbed ham) too thick.
We're not exactly rich (waiting with baited breath for our housing benefit application to come back atm) but there are some foods you just can't do the 'value' deal on, and ham is one of them.
I've never seen the point of buying bulk quantities of something that tastes like poo, might as well have a little of something that tastes like heaven or compromise and have something that's nice and doesn't break the bank.
