Please note that shipping charges appear as $0.00 initially. After packing your order, we manually calculate shipping based on your zip code, package weight, and size. We compare rates from the U.S. Post Office and UPS through Unishippers, using the lower rate for your shipment. Our supplies are reasonably priced without inflated costs to compensate for a flat shipping fee. We don’t charge a handling fee and only pass on the actual shipping charges from the post office or UPS. If all products are in stock, your order will automatically be shipped the same day without prior contact. If you want to know the shipping charges before we ship, please inform us, and we will contact you via phone or email. No charges will be applied unless we have your approval. Thank you for your order!
