I think I have to agree with you there earthfaries. Having looked at the preview pins, there are only a handful that stand out - but no where near the amount that did for Pin Trading University or Trade City last year. I think I am more happy about my early registration, breakfast and dessert pins! lol
We went to Pin Trading University by pure chance on the last day that it was open to the public. We had such an amazing time in those few hours, that we said if ever we got the chance to do it properly i.e. the whole event, we would.
I think its safe to say I'm more exciting about doing everything other than buying those pins that are limited to purchase. I don't think I would disappointed even if I went there and bought none of the event-specific pins, because it's all about the experience - meeting other traders, trading pins with traders and on the boards, just having something in common with someone who will undoubtedly have such an interest as you that you could both talk for hours!
I am looking forward to buying a new pin bag (prior to the event) and getting the chance to fill it with my christmas chocolate tin that is currently filled with swappers!
