I am in market to buy some BFS tackle and I have chance of 10% discount today, But I always got my stuff from TW and I am not sure what is next discount, Is it worth the waiting or I better get my rods and reels with 10% today?

The best is to get the gift cards at Christmas when they are 10% off.  Then in March or so when they run 20%off sitewide you apply the gift cards for almost 30% off anything they sell.  

Their sales seem to be a bit random these days instead of what used to be a very convenient 20% off site wide on BF. Might be worth looking at out of state places like the hookup tackle (typically have 20% off gift cards to then purchase anything), omnia, etc plus you'll likely save on sales tax for an additional 8% or so off. Absolutely loved TW for 10-15 years and now I miss their good ol days and tend to find much better deals elsewhere.
