We may choose a different carrier from what was indicated depending on the time of the day the shipments are booked in.
In-store pickup is free of charge.

Stock statuses and availability

We do our best to ensure that our stock counts are up to date, but mistakes can occur.
Items indicated as being “In Stock” means that they most likely available in-store and ready to ship, however errors in stock count may be present.
A realtime check of stock availability will be done before checkout, if an item is backordered you will be informed before checkout.
Items indicated as being “Available To Order” are not physically in our store, but may be ordered from our suppliers. Orders may be placed online, over the phone, or in-store. These orders take more time to fulfill, especially if they include products from an overseas supplier, or are on back-order. Items from local suppliers normally take a few business days to fulfill. Overseas suppliers may take from 10 days to several weeks to ship, especially for bulky items that need to arrive by sea. If you need your items in a hurry, please contact us for a delivery estimate. Some items may be drop-shipped direct from the supplier.
ETAs are an estimate only.
