The last time we ordered bulbs from Lightingsaving was about a year ago. We try to get the best deal he has. Sometimes he has free shipping and sometimes he has
$5.00 shipping. Once, it was a better deal to get 30 bulbs rather than 50, so we ordered two lots of 30.
On eBay, click on 'advanced search'; on the left side, select "by seller" and type in his ID: Lighingsaving and click 'search'. This will list everything that he has listed. Then, type in 10w g4 and click search. He lists quantities of 10, 12, 20, 24. There are different prices for the same quantities. I don't know why there are inconsistencies with his listings. Just look for the best deal he has.
