3 units per offer per month for EPP. For corporare+, it's 5 units per person per month. That's how it used to be.I read somewhere that the corporate offer is applicable upto 3 purchases or so per year.
Last weekend I bought screen guard(1 box unit having 2 SGs) and a case. It makes it 2. When put in cart, it shows as 2 products. Not sure if it's considered as 3 by their "system". Or there's something else to the story..
