Combined purchase of 10 units?

Hi guys, so I am just kind of confused, there’s a product I want to sell on Amazon, it’s my first time and I don’t want to spend big immediately.

So the product from the wholesaler is in packs of 6, £5 individually so it’s £30 for 1 order.

Can I buy 2 of them costing £60 in total and 12 of the product? Would that get approved as 12 units or not and being only 2 units?

Otherwise ordering 10 units of this would be £300

Thank you
