I want to buy 4 different BIN purchases from the same Seller, how can I get them all in one transaction so I can save on shipping?

Is there any mention in the listing that the seller offers a combined shipping rate?  Some do, some don't.  You can use the Ask a question link on the right side of the listing page to contact the seller, if there is no information relating to this in the listing.  Tell him what you would like to buy, and ask what the combined rate for those items would be.

Is your seller in the US?  If so, ask what it would cost to have all these items delivered USPS First Class International. (It's much cheaper than Priority, and you are cutting costs, you say).

Some listings clearly state that the seller offers a combined rate, what it costs for each additional item, and when you buy you pay the lowered amount at the check-out.  These sellers consider redundant questions about combined shipping to be an infuriating nag.  So read the listing, top to bottom.

Don't confuse Combined Shipping with Discounted Combined Shipping.

Most sellers do pass the savings from shipping multiple purchases together on to the customer. But a few will charge full shipping for each item and combine them into one package.  Not often, but that is what Detailed seller Ratings are for.

If you get a discounted combined shipping rate from the seller it should be for an exact amount such as $5.97 ,not a rough estimate such as,around $6.00.
