I am migrating to Portland and want to decide whether to bring laptop or buy ...is the acer aspire e5-575g-57d4 available here?

Don't know you should probably check the website. I don't work there. And there's lots more online than there is in the store

There are wide variety of laptops available at Best Buy

You can order it online and pick it up at the store.

Thanks for confirming...i will buy that model from there now . Thank you very much. Does it have he exact model coz i dont want the i7 variant nor i5 6th gen .

Yes, Best Buy has it.
