Where I live ( France), at the height of the season, and assuming you live in the south, good tomato will cost about 2-3$/kilo. In winter you can indeed buy tomatoes (for more money) which look like tomatoes but are tasteless and are therefore a different kind of product. It might be possible to get good tomatoes as well, but I assume this will incur a significant premium, at which point I no longer consider them affordable.
I sometimes use tomatoes for my winter dishes (pizza, Ukrainian borscht and Indian Dahl), it used to be terrible. I've since learned that most canned vegetables do not have anything added when canned (not even salt or similar, it's just hot water basically), changed to that, and now I cook almost as much in winter than I do during summer.
I understand what you mean, I may not have been very clear at all by adding product quality to the mix. So let me try again.
At least in France, there are price fluctuations : typically in season is 2 eur/kilo and off season is 4 eur/kilo (and these are current prices), which means twice as expensive.
My question to the poster living in Sweden was, given that we are in winter: are in-season tomatoes 10$/kilo as well, or is it only the case for off-season tomatoes, and in-season are still 5$/kilo, which, while expensive, is much more affordable ?
Grown in massive greenhouses require electric etc thus the cost has gone up because the cost of fuel has gone up, including transporting these things across the continent.
