Sony just updated PS Blog about the BF deals and no mention of PS+ being on sale in PS Store.

Just my two cents, don't wait anymore and go get it on Amazon.
Living in Indonesia, I hope Sony doesn't track my IP because I really want to buy 2 years of PS Plus. The exchange rate from USD to Rupiah is currently the highest in last four years.
