You can tell them you’re not wasting any of it because eventually it will be used, none of it will get spoiled and people tend to actually need that bog roll within a week or two. Also, it’s a ONE time “double” buy, because from then on you buy everything once just the same; you just make sure you don’t end up spending even MORE when you run out of the 24 roll TP bag and have to quickly buy a less eco 6-pack.
I’ve been using the Casio W800 series (W800-H currently) for the past 12+ years. This is my 3rd watch, only because I simply lost the first two. However, it’s about the 6th strap, so it’s like the AK’s strap.
