B1G1 coupon stack question

[atashi]

not sure if this is the right place to ask.

I have 10 SB toilet gel B1G1 coupon. I'm planning to use them at LD, so I'm just wondering which of the following is the correct way to use it.

1. Buy 10 and get 10 for free

2. Buy 1 and get 10 for free

I've never used more than one B1G1 coupon so I'm quite confused. Or is there a third situation?

Thanks.

I don't think you're allowed to stack BOGO coupons, but I don't know if that just means 2 different bogo coupons for the same item.

I don't think you're able to chain them though. So you'd have to buy 10. BUT I think there's coupons available for them that aren't bogos, so you could stack on the non-freebies and then get the freebies free with the bogo.
