We just switched over to a cheaper flat rate shipping model for all our US based customers. Now all general orders will cost $6 flat rate for shipping ($8 for orders containing full box items). This is a great deal for you the customer and will save you quite a bit on shipping! Priority mail is still available at standard calculated rates
Hold order customers still utilize calculated shipping but receive their standard discount of $5 per $50 spent on product.
We are in the process of working on deals for international customers by setting up alternate shipping methods that may save you a few dollars on shipping rates, but that's still in progress. More info as that becomes available.
