I'm thinking about ordering some premium jeans from online during NAS. However, as a short-legged petite, I will most likely need alterations (28.5-29" inseam). Two questions:

1) I've heard that the free alterations on regular-price items also applies to NAS, is this true? Otherwise, do I need to be a cardholder and use those free alterations?

2) Can I bring in online orders several weeks after the fact to be altered in-store? Where I am for the summer, until mid-August, is 2-3 hours away from a Nordstrom, but when I go back to the East Coast there will be one at my local mall. I was thinking that I could order a few pairs of jeans and try them on, send back the ones I don't want, and then get the keepers hemmed a month later. Will this plan work? (And do all Nordstroms have on-site alterations? The one I'd be visiting is very small, as far as department stores go.)
