Yes, you can use a Walmart e-gift card in a store. It will be linked to a specific code so you will need to print out the e-card before you try to use it in the store. This is okay because even if you print it 200 times, it is still linked to the same identification number and thus the money loaded onto it can only be spent once. It is also nice because this way you pretty much can’t lose it unless you delete the link to it or something. Even then, Walmart.com could still help you out.
