I hope this answer helped. If it did, I would love if you would consider adding me as your personal shopper with Shop Your Way. It is a free benefit of the program where I can help you when you have questions like this, give you advice on purchases you want to make, let you know about great sales and big points back deals, and send you money saving coupons weekly to your email. I even have an FB group devoted to my clients. If that interests you, signing up is easy. Just follow this link and click become a client. Hope to talk to you soon! syw.co/SaraSolida
