American Coins from 60's on Ebay 0

[Michaelcoins]

Hi everyone

I collect US Coins from 1960's. I buy them on ebay in large quantities and sometimes the auctions end at the same time and I just can't keep up with several at the same time. 

How do you manage this problem? I heard auction sniping would be one solution. What do you guys use? I found http://isnipe.io/?16 What would you recommend ? 

Thanks

There's that Spam Can again along with the same spam that was posted last month.

Not sure about you all but I report these everytime I see them.  Most often a different user but but always the same link to a .io domain (British Indian Ocean Territory).
