For Oakley and Saga go onto their website and find a customer service address to do a SASE to. I know Oakley sells their stickers for like $5 but i got 4 for free because I wrote a nice letter and all that. Try the same for Saga.
Usually they throw in a die cut with each order too.
Also, you can probably save yourself a huge hassle... just type in "stickers" in the search bar, a load of people are selling them for pretty cheap on here just find a thread and send them a message telling them which stickers you want. Good luck
