It went from like 2-3 per year to maybe one per year, to now there being zero that I'm aware of. I used to get emails, or see sales talked about on others sites -- but nothing lately.
I've just been in the habit of
buying from Amazon. The last sale DeepDiscount had, even with the % OFF coupon, prices were still higher than Amazon at the time, because Amazon dropped prices to match the DD sale.
I did buy a LOT from DD back in the day, though.
