Some great advice from Leslie, and agree, make sure you are still price competitive and stay close to DQ as they will no doubt be rolling out a domestic marketing campaign soon. If you are not already a member of this group on FB might be worth joining, https://www.facebook.com/groups/647725352678015/ has over 800 members ow and you might even be able to offer some industry rates to fellow industry people for when restrictions are lifted.
You might like to offer a free bottle of Central Otago Pinot Noir to sweeten the deal on your website, possibly run a competition on FB to win a free night to grow awareness of your product and any deals you may have. this site has just been launched and is about to get a lot of PR so you might like to do something for these guys who are supporting health care workers with great deals to say thank you http://www.thankyouhealthcare.co.nz
Best of luck.
