TB stands for Team Buds' which is basically a "perks" membership thing with a bunch of exclusive options. More on that here: budsgunshop.com/catalog/teambuds.php

George, Buds has a "Team Buds (TB)" membership that affords many benefits such as access to low stock firearms of which TB members only can either buy and/or place on layaway. You can take a look to see if membership is of interest to you here(benefits will pay for itself many times over) : budsgunshop.com/catalog/teambuds.php

Layaway TB Only means that you must be a Team Buds member to place the gun on layaway budsgunshop.com/catalog/teambuds.php if you are planning on doing a layaway I recommend joining TB as you get free layaways (non TB members pay $25.00 in fees for each 90 day layaway) team buds cost $29.95 for the 1st year
