That was my problem at VT2B as well with no motorbike. The only reasonable market around there is that pricey foodmart, more for just special items imo. Some people don't understand walking in the heat for some reason, they just look on the map and think it's an easy walk or think you can take shortcuts over on side streets, etc. You can't typically do those kind of shortcuts in thailand as they are blocked or have a lot of dogs, etc. As for the baht bus, it rarely or ever goes down that street towards lotus.
