This is week my #LEGO hobby has been pretty frustrating. I've made a few inventory errors that are taking a while to resolve because I've had to order the missing parts, but then one of them was the wrong color, and a couple more orders I received were disappointing, with missing or damaged parts like an $11 (!) rare stickered part that was listed as damaged. And that's without counting the packages from Canada that take an unknowable amount of time to arrive, unlike domestic packages that have tracking and pretty accurate delivery estimates.
I've also had a weird interaction with a Czech buyer who placed an order for an expensive set, then didn't pay the invoice, so I reported them for not paying the order. The report went through after complete silence from them for a full week, which allowed me to put the set back for sale, and then they placed a new order for the same set. This time I sent them an email before issuing the invoice, and they ended up haggling over the price, which never happened to me before. After agreeing on a price, I issued the invoice that they paid the next day, but then I realized I was missing a minifigure for the set that I apparently sold independently 6 months ago (!).
I've ordered a replacement figure and I sent them an email to inform them of the delay but I haven't got any answer from them in a few days. Granted, most buyers and sellers have been responsive and I was able to move their case forward, but the silence of the few others always gets to me and I haven't been feeling good about the whole endeavor. Now, if it had been any other activity, I might have already given up, but I've invested so much money and time that I feel like I have to power through, and I can't wait for better days.
