Absolutely!  Check out as usual and leave us a note that you'd like to pick up.  We'll refund your shipping charges once you pick up your order.  If it sits for more than 2 weeks, we'll just ship it to you.
However, we realize stuff happens, so if something comes up and you find that you will not be able to pick up your order within this window, please contact us before the 2 weeks is over we may be able to work something out.
