If I am going for a product that costs me some money, I always make the seller give his/her clear toughts about their own products. All I ask for is a bit of their personal opinion about what they are selling. If the seller can only tell me good things about their product; then they don't know enough about what they are dealing with. If he/she can tell me honestly what they think about the good sides and the not so good sides about making a purchase with them, then I will be happy to buy there.

In general I will always pay for better service, and for the professional service. That a seller gives a clear advice is crucial for having me as a customer.

Just like when I was a guide and should sell souvenirs to tourists. I would always tell them the whole truth, not what they want to hear. It's better to let them buy a $5 knife and they knowing it's a fake chinese made. If they really want a good knife, buy the one at $50.

Kiltmakers that help others here on the forum without directly benefit from it will always be the first ones that comes me in mind when I'm advicing others where to get their first kilt.
