Hi Nick, <br><br>My response was stuck on my draft folder. Thought I hit the "send" button already. My apologies for a belated "Thank you!" for this information. <br>It is valuable information and I am grateful for it. <br>
<br>Sameer or others, <br><br>Please let me know if you'd still like combine efforts to purchase this things in bulk. I can place the orders and distribute them in our Feb/March meeting. <br><br>Best, <br>Cherry<br><br>
