PLEASE NOTE! Buyers of items shipped outside the USA are responsible for customs fees/taxes/duties and may encounter delays due to customs inspections. PLEASE be aware of this! Please contact us with any questions!! Thank you!!! PLEASE NOTE! Due to outrageous shipping costs in todays economy, oversize boxes are nearly double what is used to cost to ship...for that reason, States in the Mountain and Pacific time zones are sadly costing buyers more for shipments. We do apologize for this but the truth is, it costs more just to ship out West...which we can not justify making folks in the rest of the USA pay for with "free shipping" as a part of the total cost just to cover the Western States costs. Thank you for understanding!
