Kohl's increased their initial sign-up offer up to 35% off first purchases for opening a new charge account.
This could be in response to Kohl's soft sales during the first quarter of 2019.
It will be interesting to see if this helps improve their lagging sales in certain departments.

Keep in mind that many store credit cards change their new account bonus offer seasonally and these won't stay current for long.
As per the American Express Rewards information webpage, Walmart is considered a Superstore and doesn't qualify for additional bonus points on purchases.
Now if you are serious about gaining rewards and find yourself shopping often at Walmart, you might want to check out the walmart store credit card, which offers a solid rewards program for your expenditures.
I do warn you though the interest rates for credit cards are terribly high, and if you intend to carry a balance you will be better served by choosing one with as low as a rate as possible.
I hope you enjoy your grocery shopping!
