The “big deals” seem to be generally 30% - 45% discounts across different product ranges. There are some teasers of some Prime Day sale items, but no actual specifics or discount details yet.
On a related point, coming back in here reminded me that I meant to go check if the local Prime subscription still gives me a free monthly Twitch subscription to use. It does. So go use yours before it expires!! And go claim your free Amazon, Epic and GOG games too.
Tick the “Use Prime Sub” and you should be able to “Subscribe with Prime”.
I’m resubscribing to @murfle’s DiscoBear_PS channel this month, but if there’s any other MEWb actively streaming on Twitch with a monetised channel, please let us know and we can keep sharing the love.
