Good catch. I read that page and thought it was time limited, but that was just the campaign for the base level cards.Viralriver wrote: ↑Thu Jan 27, 2022 1:38 am ...there's a different campaign for 2k points for opening a gold card, and 3k for a platinum (or 4k if you're a Diamond member)...
As with everything Rakuten, you have to read the T&Cs carefully
Beware for the 4k Diamond member promotion. That looks to be for a card switch rather than getting a second card. If you switch you'll have to update the card details with 楽天証券 to continue getting the points there (and for any other recurring payments from your current Rakuten card I guess...)
Anyone with an ETC card (through Rakuten or another CC company) should definitely look at the ETC Mileage Service (https://www.smile-etc.jp/). It works out as up to 10% cashback on expressway tolls.
