MoneyGram/Western Union and tor

[Lunar]

I searched around and couldn't find this discussed anywhere. Actually I'm not sure we're supposed to discuss this at all, and in that case, mods, please delete and forgive me.

When signing up and using money transfer services like Western Union and Money gram is there any benefit to doing so using tor? They're already going to have your bank account info anyway, so would it matter?

Also, has anyone found a benefit to using their services via a walk up location over the available web based credit card option?

Thanks
