Infant car seat and stroller help needed

Which infant travel system is good at Walmart? I've already put money for it on a Walmart gift card which is nonrefundable and now all I hear is urbini, baby trend, graco and evenflo is junk which leaves me at what now? I can't afford chicco or britax or the more expensive brands, especially with this being my last baby. I want an affordable infant car seat and stroller but am unsure now what to do. What is you ladies opinion? Do you like any of the Walmart brands? Edit: I might use the stroller once a month would I be better off the buy a better car seat and get a nicer umbrella stroller or stick to the car seat stroller combo?
