My spam filter is definitely not eating them.
I finally heard back with a tracking number and it also showed up yesterday in My USPS. She said that my box had gone out Tuesday night, but the tracking clearly shows it was picked up late Wednesday afternoon. It should be here Friday. She posted on Facebook last Friday that about half the sub boxes were going out that day and the rest through the weekend. No one has posted about receiving one, so that's a little weird.
Last month I also didn't receive tracking and nothing appeared in My USPS. I emailed Potion Dust after everyone else started receiving their boxes. She couldn't find a tracking number for my box in her records, so she contacted House of Usher. She wouldn't send me a number but said that it just "wasn't tracking." Potion Dust sent me a "second box." The "first" never appeared. I'm pretty sure it was never sent. I received the shipping notification/tracking number for the second box with no problem.
I understand that external factors do sometimes cause delays. I'm just getting a little tired of all the excuses and the truth stretching. I cancelled before I was charged for May and other than the April box I'm just waiting for the Southern Comfort sampler. It sounds like that may be awhile even though she sent some out already. I have enough wax and I am ready for a good long break.
