You don't need a big Credit Line on your Credit Card to make big Payments !
I guess most of you had the same experience at least once. Not paying your Dominican CC on time
and being feed with outrages 10+ % of the outstanding Balance. If you need to make big Payments with your CC only once in a while, you are just fine with a CC with a 300$ Spending Limit.
You can make a 5000$ payment with your card without any Problems, just deposit this amount directly at your CC. After your Deposit, you have to make your Payment before Midnight the same Day !!!
The neg. thing about all this is that you can't use your card for one whole working day after this Payment
because your Statement will show a neg. balance for 5000$.
With this Solution you will never have to pay this ridicolous late fees for not paying your CC on time.
I am working with Master and Visa from Banco Popular and i have no idea if this works
also with other Dom. Banks. Do not ask your Guy at the Bank to confirm this Method, they don't know that
this is possible.

Why give the credit card companies the satisfaction.. Use a debit card linked to a checking account that you do not have all of your funds in

I made bad experiences with debit Cards and international Payments.
Many times my Payment was declined even i had enough coverage.

Wire the money into a Dominican bank and use the Dominican debit card
