I went to Pac Yam a while back to look for a specific helmet as other shops either did not have it in stock or did not have the right size. Pac Yam was the 5th place I went to that day and I finally find the right helmet with the right size.
When it comes to paying, I asked for a discount or price match as their pricing was a little bit higher than other shops I went to that day.
I was told that they don't do price match and they would only give discount if I purchased a bike from them before. I find that to be quite funny, because I know that their pricing are not competitive to begin with and it seems that I would need to spend $10k to buy a bike first to get $20 off a helmet (which would be regular price at other shops before any discounts).
I still bought the helmet but I don't think I would go back there to buying anything unless my money is burning a hole in my pocket.
