hi all, i'm looking for a spacious tote but i don't have the GST yet. i have a petit shopper but it can't hold all that i need with my kids. i have the medallion tote but i can't get into it easily and it's more of just basics fit. i heard the gst can get heavy so is there an alternative tote to the GST or should i invest in one? what GST colors are usually available? i prefer lambskin b/c i find it lighter to hold than caviar. what's the price difference? thanks.
