Welcome to Geekhack!
There's lots of group buys to participate in, even more now that Massdrop has come along. This probably won't be the last group buy you'll be in, but please have some patience. Depending on the GBm some can run for months, and even a year is not out of the question. Fortunately most people that run group buys these days are aware of how difficult it can be, so they usually have backup plans should something go wrong.
