Recent revisions of the daily briefing has indicated that mylar bags and O2 absorbers are increasing in price. Please see the below two invoices from April and August. I buy direct from Sorbent systems / IMPAK https://www.sorbentsystems.com Pricing has not changed between April and August if you buy direct from the vendor. I do not have a special account setup or anything like that. In fact I used two separate 'guest' email accounts for each transaction. That is my experience. Keep stacking it high!
