Trade Portal Pricing

So I’ve just recently found out how much trade portal prices can vary (a certain titanium item at one portal sells for 1.5x the price at another and is giving me an insane rate of return).

Do y’all fully upgrade multiple troll trade portals to test out which ones can give the best (most beneficial) prices for items you regularly need? I’m thinking about doing it but it seems really expensive TC wise to max out trade portals?

Yeah, I did that before. In the end, I spent all of my time crystals.

Yeah, upgraded two more…welp. Great way to spend hundreds of TC lol
