Well, I spent 3.2 million on them, at 97 each.. so, a lot.. But I think I will only take about 20 minutes or so because the user I'm using right now doesn't have that much space in the locker, so It'll only take about 4-6 trips from the retail shop to the locker when I go to your town.. (I hope you get what I'm saying, lol)
And then when I go back to my town, I'll switch to a user with a lot more room, and hopefully get every last turnip
