trouble ordering parts...?

I have been trying to place an order for a CPI fuel injector unit for a 4.3 V6 Wseries...with gmpartsdirect.com and now rockauto.com and neither will accept my good credit card??? they keep saying address must match and zip code does not match...with the billing on my card...

Any ideas why? It has always worked b4?

call your credit card company and ask them what zip code they have on file.

thanks I got it straight...and it was that I had a $200. limit per day on my card...I got my bank to up my limit to $400.
I kind of like the instant cash part to be at $200. max...helps me limit my quick money..and makes me think about it...
