Dried Porcini Source?

I always have dried porcini mushrooms on hand, and need to replenish my usual mail-order of a large bag in the 8oz. range. I’ve ordered from OliveNation before, and they taste fine, but I did feel that the sizing of slices was sub-par for the grade. That may have been a one-off issue, and OliveNation was fully ready to replace the bag (which I actually didn’t bother to do, because I hate packaging and mailing things).

But it does make me curious what sources you all have found worthy for mail-order dried mushrooms.
