Couple of years ago I bought and brought home some Japanese crackers and we completely got addicted to them (while they lasted).

Now, going back we need to re-stock again. So, dear well informed public - is there a store/mall/supermarket in Tokyo well stocked with different variety of crackers and do not have astronomical prices? I do love crackers but not really to pay $10 for 80g package.

It will be highly desirable there is there is an option to sample at the place. I tried different crackers after the original purchase but they either been not the taste I've been looking for or they stuck to teeth and it was awfully difficult to remove them.

Thanks.
