I have a couple of guys...well more than a couple , that do realy well with those honor boxes. We place those to at the same price as bulk. 5 for $150.
Honestly though it is hit or miss with those. Sometimes we knock em out of the park and find 5 great locations and sometimes we end up refunding the money because we just cant pull it off. I only ask for 10 business days and if we have not made a big dent in your order...that is not even have found one. I refund the money. I dont know if it is the area or just luck that it goes one way or the other and I always put the same guy on those.
The other thing my clients that do well with those tell me they do is "deputize" someone in the office. that si give someone you kinda become buddies with there some free stuff each month to keep an ete on your box a bit. You know if they see someone getting something they remind them to throw in a buck or the vendor will remove it and that blows it for everyone...something like that I was told. the vendor that told me that said "yeah it sounds corny but it really workes".
hope that helps
