I am not entirely sure if this is a British Columbia thing or an Alberta thing, but it sure seems like people pay a higher premium bidding online then when standing in the facility bidding in person. Although convenient, I found prices much lower on lockers in Alberta. I prefer being there in person because I can get the 3D visual and smell. Not being a smoker, smell was a big part of my bidding in person. I have passed on many lockers because its harder to sell items that smell like cigarette smoke. Thats something you can't determine when bidding online.
So, in summary, online bidding can be counter productive because more people bid on lockers that they would otherwise never bother to go see in person. Its driven up locker prices, narrowing the profit margin and in a lot of cases, you make nothing and end up in the hole.
