I guess I didn't repond fast enough?

By the time he looked up the measurements of a flat rate box then measured his parts which is a starter and not symmetrical he probably got a "ill take it, let me know what the total is" maybe the guy even contacted him after you. I can tell you I'm not a fan of someone saying can it fit in a so and so box, usually the usps boxes are more expensive than sticking it in your own box, so right there your usually not doing yourself any favors. If i have two people minutes apart interested in the part the one that says "i'll take it get me a total" will get it not the guy asking.. will it, can you, how bout flat rate. etc..
