Getting ride in Bansko

I m staying in Bansko and have car in USA so don't want to buy another. Cabs are ripping me off bad and want to find a place to post where i can share a ride with someone once or twice a month to get to the Lidi supermarket 7.7 m away . Anyone know of a way? Thanks

All yellow cabs should be metered and therefore you should not be getting ripped off, but pay per km . How are they ripping you off?

bus statoin to  Saint Ivans was 14 and yellow cab from station didnt have meter. I think its about one and a half km but sticker on cab window said something like 3.5 km. I told driver but he said that was the price.
