Caught Out
I got caught by this last year just before Christmas. In some ways it worked out well because I cancelled right away and got any Christmas orders delivered free last year, but it's starting to again offer more free trials.
Tempted to sign up for another free trial this year and buy lots of minimum spend items and see how many deliveries I can get done in one month. Might also work as a bonus for the drivers as I expect they get paid per item rather than per address.
