Can I still buy iPhone 8 Plus???

Yes.

Explanation:

The text clearly states "...will remain available through select retailers..."

A retailer is defined as "a place of business usually owned and operated by a retailer but sometimes owned and operated by a manufacturer or by someone other than a retailer in which merchandise is sold primarily to ultimate consumers."

So, what the message is saying is that even though Apple themselves don't sell it anymore, other retailers will be selling it.

Hope this clarified! :)
