I am about to order the polka dot wedding invitations for my wedding but I want to get them to make some changes in the invitations but they say that will cost me a few extra bucks. Even thought they have told me about my possibilities, I want to be double sure about it and thus I am asking this. Will you tell me how many changes in the polka dot wedding invitations does not require any extra charge? Or are there any other options that I should I try that will suit my needs?
