International buyers: Please use Pay-Pal only. If you win several items, we will combine them in a single package to save you money on shipping. If the combined postage total exceeds $9.85 for domestic shipments, we will switch to the flat rate box. We're happy to hold an open box for you, just ask. Often times we are able to put a number of slabs into the $4.95 flat rate envelope with a good shipping survival success, due to careful packing. These same comments are utilized with international shipments, but have weigh restrictions of 4lbs for flat rate envelope, and 20lbs for the flat rate boxes. Please enquire.
