Genuine good intentions from BBY, but....
Ordered a headlight bucket & run/stop switch, both of which were supposed to be in good condition. The HL bucket showed up, but the run/stop was nowhere to be found.
Brenda apologized, is taking back the HL bucket because it wasn't in the kind of condition that I expected and extending me credit for other parts that she does have... but haven't shown up yet.
Separately, I ordered a spark advance that was as advertised and works fine.
In conclusion, assuming that the "store credit" parts show up and are as advertised, I'd say that they do their best over there.
