Did my weekly shop online last night, and since the money just doesn't buy as much as it used to, I added mostly "Smartprice" stuff to keep within my budget. It was delivered this morning and in the usual hurly-burly of getting it all in (whilst preventing toddler and terrier from escaping) I signed for it without paying attention to the substitutions.
When I unpacked, I found that a few of the smartprice staple items had been substituted. For the NICE ham stuff. In larger quantities. As a result, I'll be able to cook at least 2 extra (nice) meals for my family before the next shop. It's a small thing, but it really does feel nice.
