When you purchase your tickets in the store, I was thinking that it would be helpful to see when you can buy another set of tickets. Kind of like a time stamp? 

Have it say something like: 

"You are able to buy tickets on 8/14/14"

Just look on your page, you can buy them 30 days after you last bought them...

^ What Addy said.

If you look on your homepage it shows when you bought them --> http://prntscr.com/4buu3r

If you see 0000-00-00 there instead of a date, that means it's been more than 30 days, and you can buy tickets again. :)

The store will also tell you if you try to buy tickets too soon. It will say 'you already bought tickets this month. you can buy tickets on xx-xx-xxxx date' :)

Well that shows how well my brain was thinking... thanks guys!

No problem! :) Everyone has brain farts!
