Some larger, heavy, or valuable items will not be included in the above postage costs, valuable items will be sent via a fully insured and tracked service, and be insured for full value, and cost will be listed on the item page. Heavy or large items will may be sent with alternative courier at a fixed cost, this price will be listed on the item page. At the payment option page there is also an option for "cash on collection" for larger items, or by prior arrangement with me, any postage cost may still be shown on the invoice, these will of course be deducted when collected. I mainly use couriers, as it's very easy for me to drop items off at the drop off points, items will be sent via tracked service, and a fully insured service for the more expensive items. For very expensive items (£150-£500) then Royal Mail special delivery may be used, and this would be displayed on the item page along with price.
