I'm afriad no one here can really answer that for you, it really is up to you. You need to take time to weigh up the risks and the benefits of all the stores near you, and maybe go on a scouting mission to a few of them to take a quick peek at what they have.
Takking an opaque bag, or a backback with you is a really good idea. It means you won't get caught as easily AND it's goood for the environment, so good for you
