Im trying to place an order on Robot Kingdom(my first through them) but the check out isnt working..... there no reason i can see although after submitting the country/phone number details is when things start to loop.... maybe theres a data field im missing but im not seeing it.

Ordering Fansproject G3 trailer
PE Rumble/Frenzy
PE Eject/Rewind
Nemesis Prime

all are listed as in stock and even if they werent..... it'd surely not be this frustrating to tell me.

anyone else have a problem? Im sure its just me doing something wrong but its obviously so obvious of a mistake i cant find it
