ALPACA JIGSAW PIECES: to save or not to save?

I only accumulated about 12 pieces and am wondering if there will be another event to get more? I think it would be advantageous to the game moderators to have another event with this reward as I am sure many people were not able to get the Alpaca, but would save what we got to finish collecting them this next week (or 2).

Please comment if this is a viable option, otherwise i will be deleting the useless items in my inventory in a timely manor:-D

also, i found this Alpaca video on youtube:
