I seem to remember Logos asking us to give them an idea of things that we would like to see available on the web site. I searched and searched but missed it somewhere.
Yesterday, while looking at my account on another site, I noticed that they have implemented a "credit wallet". With this credit wallet I can see exactly how much I have and can add to it via the account settings on the web. I naturally thought that this account wallet would be a good idea for Logos to implement on their web site as well. During checkout, you have access to first use any or all of your credit wallet and pay the surplus using your normal payment method.
This would help me in stewardship and resist the temptation of putting large orders on a monthly payment plan. It would encourage me to save until I have enough. With a visual reminder such as this, the more I wanted something the more aggressively I would save instead of just sigh and say "one day" and probably never get it (my current situation with BDAG/HALOT bundle. But if I had something saying "Hey Rick, only $123.77 until you can get your bundle" It would be an incentive for me to lower that number by going ahead and putting my extra money into my account.
Just some ideas.
