I know a way to buy coin/cash packs for free u just need a jailbroken iPad, iPhone or iPod. After that u go to Cydia->sources->edit->then add this source sinfuliphonerepo.com->search for iAP Cracker->install it->then launch Snoopy's street fair->then go buy a coin/cash pack, it's free and it doesn't ask for your iTunes account!!! Enjoy ;)
P.s it works on other games too!!!
