Get a new photo account with Walmart Photo Centre online and you will receive 50 free 4x6 pictures. Perfect for adding Christmas pictures to your cards. I just ordered mine for pick up tomorrow at the store.
This is for new accounts only (and it might be in Canada only, not 100% sure). Once you create your account you will notice that you have 50 free in your account. Upload your pictures and choose the closest store to pick up from. Super easy!!
Hurry up before the offer is gone!
P.S. - I think you might have to pay tax or something, I'll let you know when I pick them up tomorrow.
