We do combine shipping as follows: Each additional item is $1.00 extra but we charge no more than $5.00 (Five additional items) regardless of how many items you purchase. That means there is no additional shipping charges incurred after six items are purchased regardless of size and/or quantity.

Please send an invoice request to us for multiple items of more than six so that we can insure you receive your shipping  discount. Six or less items will automatically receive a shipping discount upon payment.
