What is your definition of "a good buy"? How do you plan to use it? (Are 230 points sufficient to meet your goal?)
Edited to add: Congratulations -- sounds like you are thrilled and excited by your new purchase. I hope it gives you years of goosebumps and pleasure!
Edited again to add: Ah! I see this is an add-on to your similarly-sized contract at VGC. Guessing you are already familiar with the program and likely made an educated decision wrt number of points needed. Enjoy them entirely! You own at two very beautiful destinations! (We visited Aulani last Sept and are now about 30 days from VGC getaway. Love them both!)
