I’m not sure which debit cards you’re referring to (e.g. Interac vs VISA debit) but AFAIK they all have fees, with possibly different structures, e.g. a fixed charge + lower percentage.

Sorry, I meant that the fees are so low it is a negligible cost in most cases.

Usually 50 to 60 cents at most, but 30 cents or less most of the time. The variable component is only 0.05% most of the time.
