The Dollar Store on Scotland in Orange has all this stuff, except for people to wrap your presents.
Nearby supermarkets should have wrapping paper. Dollar store might be your best hyperlocal source for gift bags.
Promote your business here - Businesses get highlighted throughout the site and you can add a deal.
Are there any local places, not Target, Walgreens, etc., to buy wrapping paper and gift bags? Also are any local groups doing wrapping this year? Obviously needed ASAP.
