There are many more reasons why you would go with us than others:
1) ease of payments and flexibility
2) confidence that what you buy is direct and authentic
3) lots of great deals
You should also think about how a vendor is able to sell 30% cheaper than us and still be able to make money, lots of factors at play here.
Not to discredit those that re-sell our products, as you are free to buy from whoever you like, but when you want guarantees that your hard earned money is spent on authentic quality goods, then the choice is clear.
