Virtual? Then
VMware or Virtual Box + OS
SMAC (spoof Mac address)
VPN
Clear local socks
And change the time on your clock to local time of cvv and if you are repeating the gift card process change the time a minute or so each time as this goes into the device id process as well.
but if you only want one and you have never done it before just VPN and clear local socks after that your device id will be on file. For large amounts depending on the company expect some phone verification (always VoIP or Skype IN if you plan to make a business out of it)
Walmart is good for under $200 they use IEsnare so make sure to use VMware/virtual box plus spoof the Mac
CVS cashstar is easy, same deal and got to change up virtual machines (Instant printable gift card)
Homedepot same company as cvs
but from my experience in-store pick up or next day home delivery is the way to go if your in a populated US city. But they come with there own separate problems and you need to interact.
Hope i helped alittle.
P.S In my experience if they don't come in a couple of hours there not coming.
