Textbooks

My sister is studying hotel restuarant management this year and she tell me that she want to buy textbooks that she needs for her coarse. I said, to her I can buy her a books online as soon as I get back in U S because it's cheaper to buy online than in the store. She needs the textbooks buy September and it should be getting here right away, but I'll have to ask my hubby to order for her online and ship here.
