To prevent the spread of COVID-19 we are currently allowing limited entry and curbside. You may be asked to please wait if there are parties ahead of you.
What does this mean?
Maximum 1-2 customers are permitted to enter the store at a time. If there are parties ahead of you we may ask you to please wait outside at staff's discretion. Thank you for your patience.
For entry, a well-fitted face covering must be worn that goes over the nose and under the chin. Please do not enter if you are feeling any flu-like symptoms. We ask that you keep 6 feet of distance between staff and other customers. Curbside is available if these requirements are an issue.
Please use provided hand sanitizer upon entry.
We encourage a call ahead for large orders and for inventory inquiries. This can make your transaction much more efficient when you arrive.
We are still available for curbside/pick-up. You can call beforehand or arrive and call if you are not greeted sooner.
Thank you for your patience and cooperation. Conducting business this way is not ideal but critical to keeping everyone safe and our business operational.
We appreciate your continuous support!
