Does anyone know why Swagbucks is no longer offer Steam Digital Wallet Codes in their rewards store?

Hi,

I was just browsing the Swagbucks Rewards store the other day and realized that as of just a couple of days ago, they no longer offering steam wallet codes. I can still get them indirectly using Walmart Gift Cards but it will be more of a pain because steam is one of the few Gift Cards that walmart carries that they don't yet offer in Digital format which means I have to wait 203 business days for them to be shipped to me instead of instantly.. Gamestop offers Digit steam cards on their website, but I have to investigate if they allow you to use their Gamestop gift cards to purchase Steam Wallet codes because some retailers like Best Buy won't allow you to use their store gift cards to pay for other gift cards. P.S. I was just wondering if the Swagbucks made a post on their Daily Swag Blog about no longer offering steam codes?

Thanks!
