Ours is outside and DH is at work so can't tell you any specifics, but I love our chest freezer I don't know what I would do without it. We got ours when I was pregnant with Moo and it's been full ever since. I'm not sure about running costs as we got ducted air con installed around the same time, and our power consumption has increased but I wouldn't know how much the freezer contributed iykwim?

DH is paid monthly so to save money I buy meat in bulk then vac seal it in portions, can keep it for so much longer this way. I will also buy up on frozen things that are on special and pop them in there as our fridge/freezer is only tiny!

I often do huge cook ups and again vac seal in portions. There is always something to eat for dinner in the freezer when time is tight or I can't spread the grocery budget far enough. I always write the date frozen on the bag too.

Only annoying thing is ours only came with one basket, we just bought more from a storage place and they fit fine. Usually have certain things in each so it is easy to just lift out baskets to get to the one we need. When I was pregnant I even had lists of what was where stuck to it
