I have been seeing a lot of different trash cans around D.C. On the National Mall and around town, I see a lot of 42 gallon steel slat receptacles. It turns out that these are $900 if you go with Belson Outdoors and you'll see similar prices with competitors. It can be an additional couple hundred bucks to add the right top to protect from rain and accommodate for cigarette ashes.
So a normal city receptacle is 1/4 of a Big Belly in cost but Big Belly can hold up to 5 times in volume. This is a competition that is under 10 years old and if BigBelly wants to win, they need to lower their price. Looks like they've got a pretty good savings pitch here--of course, I'd like to see sources for the "Notes and Assumptions" section.
