not to be a dick but
There are no bumps allowed, not to answer questions, not to deal with thread shitting, nothing, with 2 exceptions:
1) Addition of goods. And we can detect bullshit. If you have 30 ties, and then add one a day thereafter, I consider that gaming the rules.
2) Price drops - at least 5% of the original price. If you have a consolidated thread, this only has to apply to one item. Again, common sense about gaming the system...
