I constantly found myself going into the armory to check the cost of a ship with the 25% off coupon, and eventually, I just wrote them all down and made a spreadsheet. I figured I'd share it here for anyone else that might find it useful.
Here's the link to the Google Sheets page.
If you have any suggestions for improvements, like links to reviews or something, let me know. I plan on adding links to the wiki page for each, but as for reviews, I don't believe LWM has a review for every one of them, and I feel like linking to various reviews would be a bit odd. If anyone else finds this useful and has some suggestions, please let me know. Would a sheet with Doubloon ships be useful? I don't know.
