Will Limited Time & or Limited Quantity items, recently sold, show up again sometime in the future as "Sale" items? There are some items that had my eye, because of their beauty art-wise, that I wish I had purchased when available.
Limited Time items will show up in the sales, but Limited Quantity does not. Once those are gone, they are gone.
Smart thing to do is wait till they come back around the limited time items. Unless you have a hoard of favor points saved up. If you wait you can actually buy a bigger quantity and save more then buy them outright the first time. There is a smart way to constantly improve yourself and not have to rely on store bought items constantly.
I am just about to start investing in loadout items having previously spent all of my DJs that i have aquired on Hired Hands to get to 2k. My strategy (from Mob wars) is usually to collect a bunch of points and wait until an appropriately improved limited quantity item pops up to improve my personal loadout.
