Different manufacturers have different training sites for retail associates. Each one is different. Some let you accumulate points and use them towards products, others are just there for knowledge.
The two I've been using lately are:
Lenovo's training app is new but I like it because it's easy and fast. They do monthly drawings for prizes. You need a referral code for it. You can use 49955.
Intel's retail edge is great because you earn points and can buy products at a heavy discounts.
