Jean - with great difficulty! I mostly sale shop - when the price comes down to about $14 or if there's another offer on i.e. buy one, get one half price.
icul8rg8r - yes I buy a lot from y'all. Much as I'd like to support my LQS more (I've bought my machines there and go to quite a few classes too), it's simply not feasible all the time. I'm also lucky in that DH sometimes goes to Houston, so I order quite a few things to be delivered to his hotel.
