Yes sir, if you do not wish to use Paypal, the next best way is Amazon, simply send an Amazon e-gift card
https://www.amazon.com/gp/product/B0...cg_gclptcg_2a1
to this e-mail:
paypal@subsim.com
Change the amount to what you want to donate and
be sure you include your Subsim forum name in the message section. Thanks for your interest in supporting Subsim. I will go ahead and upgrade your account now.
Good hunting!
