My comments complement Marissa's - yep, I've gotten lots of great plants at TJ's for as little as $5.99. Often they have mini-phals for $7.99 and paphs too! Bigger plants are $13.99 and REALLY EXPENSIVE ones for $16.99
. Some of the stores get stock in nearly every day but as noted - GO EARLY, as depending on the particular store, they can get picked over really early. If you go later in the day you are likely to see the plants that have been there for awhile that have not been able to get any "takers".
I also repot all plants soon after purchase - I've too often found bad root systems - even from vendors that have a history of being good ones. I like knowing right up front that any issues are mine and not something I inherited.
Like all stores that carry orchids - they also tend to increase their supply during appropriate holidays - such as mother's day, valentine's day, etc. Again - GO EARLY - as close to opening as you can.
Good luck!
