Discounts have been much less than in the past. My process is to grab a rental as soon as I know my travel dates. I look through Costco, which usually gives me the best rate and cross-check via Autoslash and Carrentalsavers. I then constantly check rates even until the day before we travel. Usually, I get the best rate anywhere from 3 weeks to 2 months before we travel. For instance, for our last rental, I started at $1,000+ for a 7day rental. Over the months prior, the rates dropped to the $4-500 range. Around 3 weeks, I got a rental for a full-size car for $301, with a $25 Costco giftcard, netting to $276. 2-3 years ago, I would’ve hoped for a rate around $225, but for now, anything sub-$300 is good.
