Fun Spot Cyber Monday - problem buying tickets

[Portugal1000]

We went to Fun Spot for first time this year and our son absolutely loved go carts. His favourite thing in the whole three weeks!! So when I saw they were going to sell the day passes for $25 I thought I would buy a few for next July. Only problem, you have to put in state and zip code for credit card and no UK option. Just wondering if anyone else was trying to do the same. Tried calling but no answer. Real shame as wanted to put in as stocking filler.
Thanks
