Clan game purchase packs timing

Just a quick suggestion on something that's crossed my mind more than once. During the games there's usually a pair of offer packs for sale, currently in my shop there's one for $50 and one for $100 for different amounts of loot, books of building, and books of fighting. My issue is the timer on the offer packs - there's a day and 19 hours left to purchase a pack while there's 2 days, 19 hrs left on the games. I'm interested in buying the $50 pack but probably won't because I can't burn 4 books of building in the time it would take to also be able to get the book of building as a clan games reward. So the suggestion, have the purchase packs run a day longer than the games, you may get more sells (you'd get one from me at least).
