Gift/premium for first 50 customers/orders

[compas]

Hi there,

 

I would like to give the first 50 customers/orders a gift if they buy from my new shop... How can i implement this? With an order above 50 Euro they should be able to get a gift.

 

Also in the future a free gift should be given if the buy more than 150 euros....

 

How can i implement this?

 

Anyone got an idea?

 

Thanks in advance,
