So it seems Autoslash is keeping its eye on things. In recent days I've received lower price discounts on two of my three upcoming reservations, (one reservation lowered twice), for my trip to Hawaii next Summer. I've booked the new rate, cancelled the old reservations, and asked Autoslash to keep watching. So far, so good. I'm still checking my go-to sites (Costco and Discount Hawaii), but everything is registered with Autoslash, too. We'll see how it works out, going forward. Fingers crossed.
