This is just as bad on frecycle, offering IKEA boxes which are very sturdy,
packing boxes, packing materials, (used but clean) bubble wrap, etc.,
you would not credit the questions! one girl wanted me to send her photographs and measurements, then couple I thought seemed regular came after we had
spent an age flattening them, rushed into the hall, ‘grabbed’ as many as they could, rushed out, not a thank you after we had waited in for them, supposed to be here
at 1pm, couldnt put them outside because of the rain.
Two conclusions -
1 - that isnt it amazing how we couldn’t get boxes for love nor money when
we moved here ( in a hurry, had to be packed and out in 2 weeks, unexpectedly)
ordered boxes from Amazon, opened them to discover they were build your own shoeboxes ?! very stressful time,
saved by the removal firm appearing with used boxes, he didnt want back
once we started buying new kitchen stuff, had pristine boxes to pass on,
like you OP, we guessed people just change their minds and don’t show.
2 - I would never do this again, into the recycling they will go !
You are not alone in your vexations, don’t be taking it personally
