the packet specifically says to look thru the ones they sent. take out what you want and send them a payment and/or send back what you don't buy. so i feel like, yes you do need to buy them.
i sent them back. if i'd known it was expected that i buy some i wouldn't have sent for this. i felt like i'd be stealing if i kept them and didn't pay for them.
