Possibly a price error but there's a lot of games on the cheap at EB this morning. All are preowned, so if you are getting them posted be aware that you could get a generic box. Still for these prices, not sure it matters.
For free shipping, refer to this deal. https://www.ozbargain.com.au/node/304597 Might be a nice thought to give a buck or two to charity if you use it, even if it's not through EB. Or not.
Good luck!
EDIT: The prices have been adjusted as of about 8am this morning on EB's website. What appears to have happened is that the price reduction was accidentally advertised as the actual sale price. Eg FIFA 17 was reduced by $57 to $8 whereas it should have been reduced by $8 to $57.
The good news is that EB have/ are honoring pick up in store orders at the mistaken prices and online orders appear to be proceeding that way as well.
My delivery order is still processing. I really hope they honour postage orders.
