I totally agree with you on that Andrea, it's definitely a good way to crank out some cash, I mentioned that in my post, but kinda glossed over it. It's a bit grindy, but in a very consistent way. And yeah, with the upgrade weekend coming up, the tech upgrades will fly off the shelves.
And for anyone else trying to make some quick cash on the upgrade weekend, here are some things that will rock up in price:
Major Research Boosts (Right now they're at around 3 mil each, usually they jump up to about 4.5 mil during the upgrade weekend)
Salvaged Technology (if you've been stockpiling this from elite STFs, the upgrade weekend will be the best time to offload them). Because they're part of the experimental upgrades, which are the best non-omega way to quality boost items.
All Superior and experimental upgrade technology. Don't waste your time crafting the green and blue ones, even in bulk they won't make you any money, but if you start crafting superior upgrades right now, you can sell them on the first day of the upgrade weekend and make a killing!
R&D packs are super low priced right now because of the Sheshar promo, they will jump up in price when the weekend comes because they are the only way to get the upgrade boosts.
Good luck and happy money making everyone! :)
