Hint that might be of interest to you: 

Stuffed animals are not fragile and can be put into a box in any position.  

Therefore, all you have to do to pay little or no additional postage is to 

(1) select some from one seller and pay for them all  at once.  

Then the seller can package them all together and save you some 

shipping costs.  But, as far as that goes, almost anything could be put in 

the same box as long as you observe (1) and (2) discussed just above.
