Returning purchases at small mom and pop stores

I’m not sure if these are also considered Sari Sari stores, I’m not talking about the little ones in houses that sell snacks and pop, but the ones that are typically in the down town area of smaller municipalities that sell a variety of electronics, small appliances and such.

These stores seem to be just personally run and I don’t know if they actually get their products from a wholesaler, or just go into the larger cities and buy from department stores for resale.

I’ve been scared to buy anything from these smaller places in case there’s a problem with the item.

Do they do returns ? Are warranties honoured ?

I want to support local small business, but at least I know if I purchase something from SM, I can return it or have it repaired if within the warranty period.

Does anyone know or have experience with these smaller retailers ?
