MINNA HELP!!

Okay they new years coming up and I've not been able to get a lot of money over Christmas so I hath a BIG decision to make =/

Do I carry on buying Duet, Myojo, Wink Up, Potato and Popolo?! =S It's costing me like 50/60pounds a month and even though it'd cost me only 25pounds if my friend sent it to me every week, I don't want to cause her trouble...

Doushiyo?! o_O
