The cost savings advantage would have to be extremely attractive for me to even consider an internet purchase of running/standing
rigging. The dimensional & quality variables and chance of error is too high.
Stock and prepackaged items are one thing. But IMHO, do not take the risk of ordering custom specific gear online. Order from your local
rigging supply shop . . . errors will be much easier to resolve and specifications more likely to be correct the first time.
