Resort Choice End Of October

I went to Paleokastritsa for the last week of October last year (half term). I had a super time and the weather was good, but as a confirmed self-caterer (budget constraints!!) was lucky to be able to eat at all. Just about everything was closed and the mini market I used only stayed open for an extra week because the weather was so good. I stayed at the Belvedere apartments and was the only person there. The owners thought I was mad and they seemed to take pity on me, leaving me plates of food several times in the week. Most of the tavernas were also closed so if I had been intending eating out I also would have struggled.
I said I would never do it again, but here I am contemplating it for this year! Does anyone know which resorts will at least have a shop that is open until the end of October. I know I would be OK in Corfu town, but I like quiet places with good walking available. Not interested in bars or nightlife, and I holiday alone.

Kalami is open until the end of October

Some of Kalami stays open until end of October but it is very weather dependant. Last year the small supermatket by the A&A stayed open until about 3rd week October, (very little stock and selling tea bags individually)!!! You will probably find Thomas' open but may be worth emailing them to confirm.
