I think they're kinda like Disney, & you can't combine discounts!
I ordered Marie Grace, her party outfit, & her dog last night for DD while the new dolls & their clothes & accessories were 25%. (Yes, she's 11, but she says she's "collecting" the dolls now!) I figured the 25% off was going to end up being better than free shipping.
My nieces are getting Kanani & Elizabeth from my mom for Christmas while DD is getting Kit (Mom ordered Elizabeth last year), so I'm waiting to see what the Black Friday & Cyber Monday sales will be.
For my nieces' birthdays, I normally buy them an AG doll outfit that goes with the doll my mom got them for Christmas. Not sure what dress I'll get for the niece who's getting Elizabeth!
