I would love to see Best Buy take on a more proactive approach to encouraging people to recycle used ink & toner. I understand that, as of now, Best Buy currently does offer a recycling program, but I would love to see them roll it into their rewards program to really encourage people to take advantage of it. This could implemented in a few different ways:
(1) Offer a coupon for an extra 5% off ink and toner for recycling. This would be the easiest to implement because if one is recycling ink or toner one would most likely be looking to purchase replacements, so for Best Buy this would offer the quickest ROI on this type of program.
(2) Offer 250 points for each toner or 50 points for each ink cartridge. This is based on the fact that ink cartridges need to be replaced quite a bit more frequently than toners and in most cases, people are replacing sets of 2 or 4 on ink cartridges, depending on if the machine is a tri-color or individual ink model. At the end of the day, every toner or 5th ink cartridge would equate to a $5 rewards certificate, which for most inks or toners is a very small discount, but it's still something to encourage people to do the right thing when it comes to disposing of used ink/toner.
Lastly, the largest benefit to either method you decided to implement would be that you would lock the customer into buying ink/toner from Best Buy and handily pull customers from office store competitors.
