We seem to receive on average 3-4 a week of these.. from a variety of charities. I've tried filling a few of these and leaving out on the days noted on the bags .. but they've never been collected. In the 3 years we've lived here we have accumulated hundreds of these bags! They've been used for storage in the attic, bin liners, to take items to charity shops etc, but it seems a monumental waste of time and plastic to keep posting these through doors ! This morning we had one delivered very carefully and quietly halfway through our letterbox at just after 6am... AIBU to think there's something suspicious about the whole thing...?
