RockyRaab,
I have no idea how far you are from Salt Lake City, but it is a mite closer than the UK to you I am sure.
I spoke with the Lady from this shop for just a minute, and she has Marmite in 250g jars, it is 13.99 though.
Maybe you could somehow get it from them if Walmart does not pan out.
They have a Facebook Page called London Market.
