Guinness Marketing: FAIL

Guinness sent me out a calendar this week as I'm on their direct marketing mailing list. The cover letter with the calendar included a voucher to get a discount on cans of Guinness[1], and also indicated that if I presented said letter at the new Guinness Merchandise shop on Westmoreland Street, I'd get a free gift (_{terms and conditions apply, while stocks last, etc.}).
I stopped by on my way to work this morning. The T's&C's required me to buy something in order to get my freebie, which, well, no big deal. I figured, you know, I'd get a small Guinness-branded item (Guinness Chocolate, anyone?).
However.
Not being one to buy a pig in a poke, or rather a pig in the hope that the accompanying free poke did not contain a non-pig, I enquired as to the nature of the free gift.

Socks.

Yes, Guinness Socks, but SOCKS. I mean, a keyring, a pen, a LED flashlight that breaks the third time you use it, fine. But SOCKS? What were they thinking?

[1] Previous Marketing FAIL: they replaced the voucher with "call this number and we'll issue you a voucher". That lasted, oh, about two months before they went back to including the vouchers with the mailer.

light my way

I have some old-style bike lights; those of the non-LED, two D-cell variety. Recently I returned from the gym, forgot to extinguish the lights, and discovered the batteries were flat the next time I wanted to take the bike out. And so last week I bought rechargables for the lights so that if I let them run down again it wouldn't be quite the same costly endeavour.
Smart, except for the bit where I had left the shop (indeed, the vicinity of the shop) before remembering I didn't have a charger with slots big enough for D-cells. Two other shops later and I was still short a charger. Eventually I ended up back in the original shop, where I got me a charger which included, as I suspected it would, a pair of D-cells gratis. Gah. I guess they're my hot spares or something.
Fitted new batteries, cycled to gym, dismounted, discovered rear light wasn't working. After some fiddling, further discovered that the bulb had blown. The main reason I got batteries rather than new LED-based lights was that these lights were still functional. GAH.
This morning: called to a bike shop. They laughed. I kid you not. They didn't have anything that even looked like it'd fit my lights, so I went to the nearest Maplin store, where they had something appropriate, and three thereof. I said, "I'll take all three" (thinking ahead!). Guy returns from the storeroom with one single bulb, and says, "that's all we have". OH well.
I'm about to head to the gym now, and the bulb works, which is good. What are the chances the other one will blow, or one or both lights will spontaneously explode, sending me back to the bike shop in search of the LED lights I should've gotten in the first place?
