There use to be a vendor on ebay that sold 20 pairs of starline tips for $1. I ended up getting 40 pairs due to them messing up on my initial order. Probably cost them more money to ship them than what little money they made.
You can do that tip mod with just about any earphones tips. All those tips you don't use that come with your earphones. Try them inversed. You might be surprised.
This vendor sells 16 pairs for less than $5.00 not bad deal.

You can buy 3 pairs of the size you need for less than a dollar here. Shipping cost $1.67 to ship it via snail mail but worth owning some of these for the inverse mod. Some of the better tips you can use for your earphones inversed. Better than Xelastecs Imo.
