I know there was a deal last month for the Wine Preservation System. Any deals on this going on now?
No, they only have one sale a year on Black Friday. This past year Amazon also had last year's limited edition on sale. I think it was Prime day, don't remember.
You can order the model one for $200 since they pretty much all do the same thing (except the overpriced electric one) or you can get one on Sunday on eBay, there'll be a 15% off coupon.
