Dealing with Shipwreck for at least 8 years, they were always a reliable, friendly site with a huge supply of products. Sadly, it's turned into a site that has more "unavailable at this time" products than in stock items!
Although the consumer is generally alerted to the "out of stock" status, it is not uncommon for the website to list an item as "in stock", only to have it not included in your order because they've run out it. I called customer service at one point to ask if they were going out of business, they assured me that was not the case. Another pandemic casualty or just very poor website management?
