Thoughts on Etsy Treasury

I have recently spent alot more time in the Etsy treasury. It is fun to look and leave comments. I myself have never been able to snag one. I have tried to no avail. So I have resigned to the fact that my computer may not be quick enough to handle getting one. I have noticed that for the most part the same people are able to get them. What are your thoughts on the treasury? I would really like to hear from you about this promotion tool. Also what is interesting are the buy and replace treasuries. I will admit that I have done these recently since I am in the process of buying gifts and presents for up coming Birthdays. So why not kill two birds with one stone right? I realize this is a sore subject with alot of fellow etsians, so I don't want to open any can of worms but once again what do you think of B & R's? I would be so interested in hearing all comments positive or negative. Thanks!!!
