I have the card and it is great. I got a high limit and if you shop at Walmart enough it could be worth your time. With the card having no forgein transaction fees that is one of the main reasons I got the cardalso the thing being I go to Walmart a lot. You are most likely to get a good limit with it and all in all I think it's not a bad card.
The 5% on Walmart.com would be very tempting, as well. I believe you can even have them fill your grocery order.
