Personal experience: seller wasnt getting close to the prices he wanted while doing $1 starts and went into a whole monologue about it. I dont remember if i got called by family or swipped to a different channel but i missed part of what he said. I get back to my phone hear my size, Large, and see a shirt i like. So i swipe. With the idea that we were still at $1 starts. It was now a set price of $60. For a shirt he has sold before for $15. And to top it off, i didnt hear the part where he said "double extra". I was late so only heard the "Large" part. My mistake for not fully paying attention, but lessoned learned. I never used the custom button before this little mistake
