Yeah, it'd have to be low value since you can't really expect somebody to fork out £40 for you

So we should all agree on a price (maybe £10 or less) and you spend there or there-abouts. As you obviously wouldn't want the chance of spending £40 on somebody to only receive a £5 gift back :/
Also, when everyone sends their presents to their person, don't write your name on it, just simply write CE.org, or something to identify it as from this forum, and we can all have a guessing day back here where we all guess who gave us our presents, before we reveal who we bought for
