Guild Wars 2

I bought some items so that I could sell them and make a profit. Last night I put them on the TP and when I listed them they did not show up for sale. I looked through the list my sale price was the highest and it did not show it. Even worse the number of items for sale excluded the 62 I put on the TP. This morning I checked again and decided to sell the items at a lower price just to break even. When I listed them it did show up, But about 5 min ago I checked them again and it was not there and worse even, out of the 128 avalible for sale it does not include my 62 again. What is going on here?

It only shows the 20 cheapest sell offers. If your offer isn’t one of those, it won’t show up.

“I looked through the list my sale price was the highest and it did not show it”
as a sale listing, highest would be the one last to show up, and as greyblue said, it only shows the 20 cheapest.
double check the price to find it on the list. I’ve seen people mistakenly do 117 instead of 177
