Reselling is in theory the most effective and quickest way to make tonnes of NP. Restocking is great and all if you manage to nab something great, but most of the time you are sitting there like a dunce pressing f5 and in the off-chance that something half-decent comes your way, it's usually sold out. Very tedious and time consuming.

On the other hand, with reselling, it's all smooth sailing once you have a sizeable stash of NP saved up. Cash flow can be very quick. Buy lots of expensive rare items and resell them within the next few days (or if you're patient, few weeks-many months for some items, but you yield higher profits). The trick is to always buy until you are dry of NP. At the same time, you sell what you have. If you have 50m for instance and you buy a lot, you'll always have a big inventory and will sell items a lot more often than someone with only a few mil since you have lots of options.

So yeah....restocking ist ghey.
