Priest:
i am with UK Fueks, Esso and EDC. No, only AllStar wanted a deposit as me being a startup
I`ve had two approach me this month, and both wanted a “bond” because of the volume we use 
I didn’t approach them, so in my book, its a bit cheeky to then request a “bond” when you are chasing the business 
Beware of “minimum usage” charges, and that other little earner, the charge for the card 
The minimum usage chancers are those that normally quote expensive prices, so there is zero incentive to use the card
