Yup, our dealership charges a 3% service fee for anything above $3000.
Even if you get 2% cash dividend or air miles, it wouldn't make much sense to do it.
I think it is the samething for some shops, eg Canada Computer.
They ask for a 2% service charge if you use CC, but no charge for debit or cash.
Their inventory is not cheap for nothing, if low profit is the way to go, they some how have to find ways to cut cost.
Small size store, low cost salespeople, 0 demos to touch and play with, inventory stacked up to the ceiling, no return but can exchange (only if defective) policy.
Typical Hong Kong business style.
Some shops are even tax free if you pay cash instead of debit. I love Pacific Mall.
