I usually ship within 2 business days of received payment. Within the US, most items will ship either first class package or Priority Mail via the US Postal Service, and usually arrive 2 to 4 business days after shipment.
Yes, I can ship worldwide. Most items ship via USPS First Class International post. The buyer is responsible for the actual shipping costs, as well as for any additional customs or tax charges from their country.
Yes, I do accept returns within 30 days for a full refund of the item price. However, unless the mistake is mine (such as wrong item sent, or item broke in shipping), the buyer is responsible for the shipping charges. I will refund full item price as soon as the item is received back in the same condition it was shipped.
