Just grabbed a PS5 and a month of PS5+ but that's $25/m.
Over in PC land there are freebies on Epic, there are Steam sales and there are other options like Humble Bundle etc.
What are the options (except Trade Me, FB
Marketplace etc) in PS5 land?
On another note, at $669 I think I've done alright for a PS5 disc console.

I watchlist games on Amazon AU, wait for them to go on sale, buy and play them, then resell on TradeMe. Most of the time I make money, or sell for a few dollars less than the initial purchase price (that's including the success fees too so you could just wait for a free selling weekend). Either that or I just buy games on TradeMe when a bargain appears. Makes for cheap gaming!
