Stella McCartney Falabella Tote

Does anybody know if the heart shaped Stella Mccartney bag is still available or is it and old collection? I almost purchased one two days ago but somebody snatched it right in front of me! I still really want it, it looks so cute
 
A word of your wisdom, please ladies - do all Stella Falabellas, even the earliest ones, have YKK zippers? Mine looks entirely genuine but the zippers are marked with single D, H, or R letters, not YKK. Thanks so much....
 
I am really liking the look of this bag. What are your thoughts? Do you find it stylish but good for an everyday bag? Any thoughts on the wallets? TIA!!!!
I have the flap wallet in burgundy and a couple of card holders - one in black with a zip and another smaller onedownload.jpg in navyP00266404.jpg . They are extremely durable and lightweight. I have had mine for about a year and they show no signs of wear. You can find both the wallets and the card holders on sale.
