password protect my entire store

[focusworks]

I'm having a big sale on my site but it's not a blanket percentage off things so I can't use coupons.  I need to go through and set sale prices on all 150ish products on my page.  I want to make it so my customers can't access my store for a couple of days while I deal with all of that so I can open it up with everything setup already.  There must be a way to do that

If you are going to adjust the prices on all of your products the fastest way would be to use a csv file. Export your items and then edit the spreadsheet for the sale prices. Once you import the file back to your store all of the prices will update. Is this what you are looking for?
