One of the reasons Isaan is cheap, is that you can find products that work for almost nothing.
Can you imagine how much a razor with 21 blades would cost in the US? It could run as much as US $37!
A razor and 21 blades should last you 6 months, saving you money.
The good news is I tried it and no issues what so ever.
Found these at the local DIY store in Ban Thaen.
If you look around, you can find very inexpensive items that will do the job quite well.
Another way you can save money living in rural Isaan.
