Please be careful when ordering any item over the web which requires you to provide your credit card number. This applies to this or any other product.
The Quality Marine Products webpage used to order these flushing bags is at the URL
http://www.qualitymarineproducts.com/bb1form.htm (this is to specifically order the BB1 size bag) .
Note that this website's URL starts w/ "http://.." not "https://". The embedded "S" implies that the website uses SSL. SSL stands for Secure Sockets Layer and is a methodology used by TCP/IP (the internet's method of communication between various devices) to encrypt, validate, and authenticate data sent over the internet.
Without SSL or some other encryption method your credit card information is transmitted over the internet in clear text which is susceptible to being intercepted.
All banks, credit card companies, and most online internet vendors use SSL to protect customer data. Besides the "S" in the first part of the URL name SSL protected webpages also will display a Padlock somewhere on the webpage (placement of the padlock is different for various versions of Internet Explorer or other browsers).
This is not an indictment of the servers used by Quality Marine Products. I am merely stating that they have not gone thru the extra effort to insure the transmission of their customer's data (such as credit card #'s) is encrypted while being transmitted over the internet.
In this day and age of mass internet usage vendors should go to all extremes to insure their customers data is as well protected as possible.
Take care and be careful,
Dan
