First catalog of the season is from Totally Tomatoes (this link did not work as of today, but maybe it will when you try it). I'm not sure I have ever ordered from them, or if I did, it was many moons ago, but when it comes to garden catalogs, that does not matter. If you order from one, you get them all.
But TT does not have the Brandy Boy Hybrid from Burpee. I grew Brandywines last year, for the first time, and while they do taste good, the plant habit (jungle-like) and the fruit characteristics (thin-skinned, they split easily and did not keep even a day after harvest) led to disappointment. But I am willing to try again, with the Burpee hybrid.
