My grandmother used to take me on an annual early December trek to Ah Sams to see the Christmas trees, ornaments and other festive decorations at the beginning of the holidays.
I have loved Ah Sams ever since, and whenever I need to send flowers to some-one they are the first place I call. They always manage to something unique and surprising with each arrangement.
They have the best selection of plants and unique planters also.
They are not the low cost leader -- but they are definitely worth the little bit extra they cost.
