Hola de Texas
How do I pay for this?
Hola MortonSalt and welcome to SpanishDict!!!
I am not quite sure what it is you are asking.....are you wanting a translation for this sentence or were you asking in regards to your SpanishDict membership?
If you were asking for a translation, you might try (depending on the intent of your question):
¿Cómo puedo pagar por este servicio? - How can I pay for this service?
¿Dónde puedo pagar por este servicio? - Where can I pay for this service?
If, on the other hand, you were asking in regards to the membership then the answer to your question is that you don't. The membership is free. Here are a couple of links that you can have a look at to help you become a bit more familiar with the site.
Hope to see you around the forum, and again....Welcome to SpanishDict!!!
Welcome to the forum!
It depends upon how much cash you have, which credit cards you have, if you have a check-book handy, and the method of payment accepted by the seller.
