I'm pretty sure I bought at least 3x Can of Dust Killer Spray while doing a once-over of today's Recycle Beast items. I looked at several items' shop search results before refreshing the Recycle Beast page, so I can't be sure how many I bought (as it only appears once in my browser history). When I refreshed the Recycle Beast page to turn in the items, it said I didn't have any of that item. What's going on?
