If you need them now, buy them from another vendor. Whoever's XLR cables arrive first will be the ones you keep and you should return the ones that arrive last, especially if it's the original vendor that you bought them from.I bought a set of monitors from a local online vendor. I've had them in my possession for over a week. That vendor didn't have the XLR's I wanted in stock when I bought the monitors so I turned to another online vendor noted for satisfying a musician's sweet tooth. I purchased the cables and they were shipped on the 4th by USPS First Class Mail.
I sell a lot of automobile parts online and while I am aware of the delays experienced by all the major shippers, I can't really say I've had a particularly difficult time with any of them. Just about everything I shipped to my customers since the first of the year has arrived, safely. That includes UPS, FedEx and USPS packages.
I contacted the online vendor I bought the cables from asking if they had an updated timeframe based on delays. They just said sit and wait or, if you really need the cables, call and we'll see what we can do. Meanwhile, the online vendor that I originally purchased the monitors from has the XLR's back in stock.
So, do I sit and wait for the original set of cables to wend their way through the USPS system or do I buy another set from the online store I bought the monitors from. They didn't seem to have any issues getting my parts to me in a timely fashion by USPS, UPS or Fedex. BTW I'm not blaming anyone. I know there are a multitude of reasons for the delay. I just want to hear what you would do.
Thanks!
Also, don't expect timely updates on tracking from USPS. You typically get the "shipped", "in-transit", and "delivered" messages and that's about the best granularity you'll get from them.
