@ ganbaru - I think you have quite a bit of choices to choose from, so just choose the one that sounds the best to you. Or modify it a bit to fit how you like it. I don't know how many more ways we can come up with to translate it. The meaning's are all right, so yeah, just choose what you like.

そのスーパーへはよく来るんですか。」
「時々来ます

This sounds odd to me. If you want to use 来る then using その is kind of weird. It should be この. If you want to use その then you should use 行く. And it might be better to switch the particle to に in that case.
