Last year i got some smoking good deals and managed to make several hundred dollars in profit reselling.
For instance, i got many skilhunt S3 PROs for $33 each
Zanflare F1s for $9.99
Imalent DT70s and DT35s for $37.
Liitokala Li100 chargers for $0.99.
There will be good deals but you have to be alert. Also, never look at the % of discount. Look to other sites where the item is sold and compare.
Like said before, if you invest your time and research for the products you want/need, then yes - there can be deals. But your time and efforts also have a value attached to it.
The best thing for us to do would be to share the deals in either this thread or a dedicated 11/11 AE deals thread so we can all benefit.
